[wxruby-users] Treads slowing down the process

[Joseph Edelstein]

Hello,

I was having problems with my GUI freezing if you clicked off of it when
it was running or if it was processing a large file.  After researching
the forum, I found a thread that dealt with the problem by adding a
timer and Thread.pass to the App.  This solved the problem of the GUI
freezing or hanging.

However, it has caused the program to run very slowly.  What use to take
only a few seconds now takes a few minutes.  People will be processing
large text files with this program so speed is important.

Thanks in advance for any help.

Joe
