I had a moment and saw that Wine is now up to 0.9.51, as of December 14.
One thing it says it fixes is "Improved support for screen resolution
This may help a variety of issues us NoteTab users have had.
I updated my Slackware 12 box to 0.9.51, and the cursor issue now only
appears to be an issue for me at the bottom of an OTL topic. Regular
text files are fine.
I have not had time to text NoteTab Light or Standard. I do not know
if there are packages for Debian or Ubuntu yet.
Perhaps this one will make a difference, let us all know!
