Hello

Wanted to say that I'm really enjoying using this software. It's a lot more controllable, and logical, than a lot of the other software I've tried. Thanks for that. Smile

I do have a couple of questions. Please bear in mind that I'm no expert with this stuff!

1. When I reboot Windows is there any way to start MinimServer without it performing a rescan? Sometimes I need to reboot the machine and I know that nothing has changed in any of the media libraries. Is there a command line switch I should use?

2. Sometimes the MinimServer icon in the taskbar stops responding, i.e. right-clicking does nothing....the usual context options are not displayed and the only way I can get them back is by killing the javaw process and excuting MinimServer again from the program menu. Unfortunately I then have to wait for a full rescan. As for question 1 any way to deal with this without having to do a full rescan?

Thanks.
Chris

You can set the startupScan property to false and do a manual Rescan only after you have added new music.

Setting startupScan to false will eliminate this rescan.

This problem with the icon shouldn't be happening and I would like to find out more about the cause. If you have the JDK installed (or are willing to install it), please enter the following command from a command prompt when this happens:

jstack <pid>

where <pid> is the PID shown by Task Manager for the javaw process. Please attach the output from jstack to a post here. Many thanks!

I experienced a few times this problem about the Minimserver icon not responding in the Windows taskbar. The problem always occured after the Windows explorer (explorer.exe, which manages the taskbar among other things) crashed on me. Following the crash, the Windows explorer then restarts automatically, but the minimserver icon then becomes irresponsive. I always reboot the pc in that case, since I tend to not trust the explorer anymore.

It would be interesting to see what happens to the minimserver icon if explorer.exe is manually killed.

If this happens again, please run the jstack command that I mentioned and save the output. Thanks!

As Andre pointed out this certainly happens when Windows Explorer terminates abnormally, which just happened to me.

After restarting explorer.exe the MinimServer taskbar icon is unresponsive. I have attached the jstack trace as requested.

I don't remember the unexpected termination of explorer being the cause previously, although it's possible. It certainly was the cause this time.

Hope the trace is of some help.

Thanks for posting the stack trace. Unfortunately, it looks normal and doesn't provide any clues. Are you using Windows 7 or Windows 8.1?

I am using Windows 7 Home Premium SP1 x64.

Not sure if it's relevant, but I also have UMS (Universal Media Server) installed (another javaw application) and that seems to deal okay with a restart of explorer. It's open source.

Also found a post (below) regarding re-registering of the systray icon on a windows activation event, although as the OP of that post points out the reply given is not specific enough.

Restoring Java systray icon after explorer crashes

I do some programmingh at work, but unfortunately not java.... Sad

Thanks for these pointers.

Is the minim icon in the system tray overflow area after Explorer restarts? This can be accessed by clicking the upward-pointing triangle in the system tray.

I have downloaded UMS and I will do some testing with it in the next few days to see how it handles this situation.

I was obviously too vague in my original description of the problem. The tasknbar icon does NOT disappear. It is still present on the taskbar - I never hide taskbar icons anyway (personal preference). The issue is that when you right-click the icon to get the context menu it does nothing, i.e. the context menu is not displayed so you cannot Rescan, Restart, Stop, Show Log, etc.

I mentioned UMS as this has a very similar right-click context menu, options such as Web Interface, Main Panel, etc., but this remains responsive after a restart of explorer.exe.

I think my misunderstanding was caused by following the link in your earlier post and seeing a post describing the icon disappearing after an Explorer restart. I will try to reproduce the problem you have described.
