Printing of tabs

[markkuin2]

When I print multiple document with a lot of tab-characters in it, my computer suddenly reboots, with no warning / blue screen or whatever. I found that when I changed the procedure TRVTabItemInfo.DrawTab(...)

Code: Select all

//  if Canvas.Brush.Color<>clNone then
  if (Canvas.Brush.Color and $FFFFFF) <> (clNone and $FFFFFF) then 

the reboots don't happen again.

The line if Canvas.Brush.Color<>clNone is always true, because the high order byte of Canvas.Brush.Color is different as the high order byte of clNone (at least on my system / printer).

I don't know which part of the system (printer / printer driver / printer spooler) crashes, but one of them definately doesn't like the printing of loads of white rectangles.

Hmm... This is not a very good workaround, because background can be colored (document/paragraph/table), and white tabs on them must be noticeable.
