current line while debugging

[Beljouani, Christophe S]

Hi,

I have a problem that appears randomly: while debugging, doing step line and
next line, when the source buffer needs to be updated to display the current
line, sometime it is updated, sometime it is not. Also, the cursor that
shows the current line is not always showed. Sometime, I can see it
appearing and then disappear. I'm using xemacs 21.1.6 and NT 4.

Thanks for any help,
Christophe
