(maybe applies only to wine, I didn't test it under windows)
After upgrading from 3.80 to 4.02, any attempt to open old world files resulted a crash. It was caused by missing attribute tab_completion_lines="200" in files saved by older versions, after adding the correct line the world opens fine.
Yes I see what you mean.
This seems to be related to other bug reported about not being able to open a notepad window.
The configuration error attempts to report to a notepad window the error message, so it seems there is a general problem with notepad windows.
Setting the default editor to notepad instead of the internal notepad will also fix the problem. It doesn't use the same dlls as the internal editor or crimsoneditor, so it won't crash. Having errors print to screen also helped me before I figured out the notepad thing. I kept trying to open up plugins that caused errors, which would then try to open the notepad, which would crash MC. Only actual bad thing I've found about Wine for MUSHclient.
I am trying to work out why it is doing this, however in the process I have found that using the /wine option seems to make the problem go away, I am not quite sure why.
eg.
$ wine mushclient.exe /wine
Does this still get rid of scripting, or has that been changed since I last ran it with /wine?
Sorry for asking all these questions. I'm still trying to figure out the source code and the MFC library. It's been a while since I've used C++, and your source is so frigging organized. I'm used to everything dumped into one big lump of a file.
It gets rid of scripting, except Lua.
