Well. it's fixed starting from revision 574 :) The culprit was rev354 where I added window resize code. Sorry for commit message, I was extremely busy at the time, using this software in my band. I coded this mostly at night and at that time I just commit what was in trunk :( The issue was cause because this plugin tried to resize editor window before it was fully opened.
allow resize only if editor is already opened
Thanks for this investigation. For now I can confirm this issue. I'm not actively maintain this code anymore, but I'll try to do something with this ASAP.
