Juergen, you asked for it :)
Some problems with tabular found why testing with purify (most of
these were not found by purify, but visual inspection)
I loaded the user guide and went to the table in 3.1.2.3.
- actrow is not initialized in InsetTabular constructor (found by purify)
- in the first column, which has a double line on the right, the line
turns to a single one when you edit a cell.
- typing in cells is awfully slow. This is probably worse due to
purify overhead, but I do not see a slowness when typing in a normal
paragraph. I suspect something wrong happens here (does anybody
knows how to use quantify?).
- if I select the two first cells of a column and then do 'remove
column', the selection gets confused. This does not seem to happen
when I select only one cell.
- after doing that (I do not know what triggers the problem exactly,
but I also used undo/redo), cells keep the red box around them after
the cursor is put in another one (I get several red boxes in the
table).
- another UMR I could not track down (see appended trace). I get
several of these, but they seem to come from the same reason.
