"XtUngrabButton(text, 3, 8) Attempt to remove nonexistent passive grab"

[Boris Deshev]

Hi, I'm running Nedit 5.5 on ubuntu 9.04.
When i open many files >10, or some very big ones i got a message:
XtUngrabButton(text,3,8)
Attempt to remove nonexistent passive grab
The message appears when i'm closing the files, which is just annoying. But
sometimes when i try to copy big multi-column parts from one file to
another, or from a web page to a file, it just doesn't copy anything and
puts the same message in the terminal. If i close the nedit and start it
again it's ok for a while, and then it starts again.
I should have plenty of memory for the job (if this is relevant)- 3GB.
Before i had ubuntu 8.10 and Nedit was working fine, the problems started
after the update.

Cheers,
