Colin,

yes. ::)

I have it in both apps, the original one and my slightly modified one. It also happens if I unzip the original app and compile with no change.

It makes no change if the programm runs within the IDE or not.

What I do is running the report and cycle trough the zooms using the "L" key. I can do up to two complete loops trough the zooms then it first doesn't paint the 150%. In the next rouund 300% blinks several times and 200% starts to endless loops. After that each change (zoom, number of visible pages) restarts the paint loop.

Sometimes the loop stops after ESC or after clicking somewhere inside _VFP

I have no idea where _SCREEN.PAINT comes from.
I have restarted the whole system to stop all other processes and to run just VFP but there was no change. In the moment I'm looking for an other comp to test there.
Have done it. On a more ore less identic XP system and on an old W2K I was not able to reproduce the problem.

All influence I can see is

Chained complex (those that need longer time to build up the page) reports seems to have more loops. Simple reports at leas binks several times.
Changes to _REPORTPREVIEW, even like

lcOldPreview = _REPORTPREVIEW

*something but no change to _REPORTPREVIEW

_REPORTPREVIEW = lcOldPreview

makes the problem faster.
