I encountered the following issue:
When I type two commas in succession in the "Strip trailing stuff" editbox (in the Modify/format case dialog), the program hangs. I was trying to strip trailing commas from a string; obviously this is not the way! :-) Is there a way to "escape" a comma so it gets treated as a character to strip instead of as a separator?
I use version 1.05.02 on Windows XP.
I hope this helps you solve the problem.
