Hi Unix Squeakers!

I have a bit of a question...I often leave my Squeak VM running for extended 
periods of time running on my Xterminal (I rarely log out).  I'm finding, 
however, that sometimes after being up for a while, the mouse events in Squeak 
get confused somehow.  For example, if I have a browser window up, when things 
get in their confused state, if I click on a class definition the name of the 
definition gets highlighted in yellow (as opposed to grey/red) and nothing 
happens (ie the breakdown of the class does not happen in the rest of the 
browser).  If I right-click on the 'root' MVC desktop in this state, the 
equivalent of the 'do' menu pops up instead of the usual menu with 'open..' in 
it.  It almost seems that the mouse click is being 'modified' somehow, as 
though the alt key or a control key were stuck.

I'm not sure that this is a Squeak-related thing, since the only way I can fix 
it is to reset the Xterminal...however no other apps I have running exhibit 
this behaviour, only Squeak.  (Then again the current incarnation of the HP 
Xterminal software is known to be extremely buggy, so I can't rule that out!)

Has anyone else seen this happen?
