Applying this version lost the ability to sort the todo list and did something to break the .ini file.

Reinstalling the current release required me to have to restore an backup copy of the .ini or it wouldn't load the program.

Hmm... I haven't noticed such. Has anyone else had similar problems with this build?

neither problem for me.
