[Lazarus] IDE problems

[brian]

Hi folks,

Something has spontaneously gone wrong with the IDE on my setup. I say 
spontaneously because I was in the middle of debugging a program when 
suddenly everything but the source window disappeared. I eventually 
had to abort Lazarus and re-start the program, but now I see some very 
strange behaviour :-

1) Pull-down menus stay pulled down, even when I've selected an entry.

2) Only the object inspector or the source editor can be visible at 
any one time - select one, and the other vanishes.

There are probably a few other quirks too, but those are the most 
annoying two.

In my Delphi days, there used to be a desktop configuration file which 
you deleted if the IDE got all screwed up, and then when you ran the 
program again you were back to all the defaults.

Is there such a file for Lazarus? I assume this isn't a 
version-specific question, but anyway, I'm running Lazarus under 
64-bit Debian multi-home, and the version is the latest as downloaded 
by fpcup_linux_x64 two days ago, SVN revision 43478.

Thanks,

Brian.
