whenever i paste something large into the scripts editor and then undo it, it crashes mIRC
(i have v6.32 on XPsp2)
I can't reproduce this. I even tried copying a 8,000~ line log into it and nothing happened.
Or are you using a specific part of the scripts editor? Aliases, remotes, etc.
Do you have a syntax highlighting DLL loaded by any chance? I had this same problem but it went away when I unloaded the DLL.
