Minimwatch problems on ubuntu gnome

[simoncn]

MinimServer update 105 includes a fix for this problem. It is caused by an incompatibility between Java and GNOME and I have added a temporary workaround in MinimServer to make these work together. At some point I hope there will be a fix in Java but for now this should restore normal functionality for MinimServer.

As tooltips (mouse over) don't work in GNOME (this one is insoluble), I have added code to MinimServer to make a single left click on the minim icon display the tooltip message.
