I have a consistently reproducible fault on both v2.2.2 and v2.2.3 under Windows 3.1, where (some of) both Input and Output cells are displayed with a proportional font (I think Times New Roman?) instead of Courier. The sequence of events is typically as follows: 1) open 1 old notebook 2) open a second notebook It looks as if a few cells become corrupted in the second notebook. These can be displayed correctly by selecting "Input" or "Output" from the panel at top left of the main window for each cell individually. 3) If the 1st notebook is closed now, the corruption remains in the second.
If the 2nd notebook is opened in isolation, no problem.
This might be a problem of transfer between v2.2.2 and v2.2.3 (running on different machines, 16 Mb & 32Mb RAM), but it does seem to be consistent on both versions that a second notebook always looks corrupted. I don't think the file contents are affected, only display. Alternatively, the notebook files may simply be too large [for Windows?].
Other corruptions, like cells spilling over into the next cell, also look like font problems - this usually affects the first file of the 2.
I have not seen this problem described before, any help would be welcome. -- I hate this 'orrible computer : from - John Tanner I really ought to sell it : home - email@example.com It never does what I want : $$$$ - firstname.lastname@example.org but only what I tell it. : work - email@example.com
