Removed it and installed the latest version. The problem persists. I can make
the window bigger, but not smaller.
I ran it from a terminal in case there were error messages worth capturing.
Here's the output I got:
alex@mona ~/Downloads/eric4-4.4.19 $ eric4
Warning: translation file 'qt_en_US'could not be loaded.
Warning: translation file 'eric4_en_US'could not be loaded.
Warning: translation file 'qscintilla_en_US'could not be loaded.
I don't think the above messages are critical, from the little I've read, but
you're the expert...
PS: not sure that I mentioned it but this is on an asus eee pc with a 1024 x 600
