May be it has something to do with multi-threading. If two events are processed in parallel, something like this may happen. Then a version of Tcl/Tk build with "-diable-threads" option should solve the problem. Regards, S. Martin Sluka wrote:
There are the same things rarely under MacOS X, but it is definitely in TCL. And it mainly if I try to do several steps very fast - click, move with mouse, choose menu item and so on.

Not sure what can be done about this apart from saving often, but thought I should report it.
No idea why this happens - from time to time it happened to me also, but it was very rare. In any case, I will probably add "Auto save" feature to xtherion.
It did it again after I sent that mail - just as I was re-drawing the scrap that it had lost! That's far too often. I have 20km of cave to draw - I am going to get very annoyed if I keep losing chucks...
Difficult to track this sort of think down I know. I'll see if I can work out what is going on. Are there any 'escape' mechanisms in wish/tcl that might let me regain control? or debug mechanisms that might tell us where it got stuck? The CPU use is not excessive, but the app is unresponsive - so it is presumably blocking waiting for something.
I could run it under strace I suppose...
