Hi Guys,

can someone test a edbSyntaxMemo within a tGroupbox (doublebuffered =
True) on an Form with doublebuffered set to true.

I have a MDI-Form with an mdi-child-form. Creation is ok but if i
switch with CTRL+TAB within forms, sometimes the tEDBSyntaxMemo is
hanging so the app stopps working.

In my case it hangs each time within the
"While TempLine <= TempEndLine)" Loop in edbutilscomps.pas in the
function "procedure TEDBSyntaxMemo.Paint;"

Can I suggest that rather than this you you post a test project to the binaries for people to look at. What you're asking requires a reasonable amount of time to 1) guess at exactly what you're doing and 2) building a project which may not reflect your situation.

Hi Roy, yes you're totaly right, i'll create a test-project tomorrow
and post it here.

In my case, setting the "DoubleBuffered" Property of my tGroupbox
solved the problems.

I was not able to create a demo with basic delphi components and
tEDBSyntaxMemo. Possible that this problem has something to do with
DevExpress Styles and DoubleBuffered and Project Theme settings.

At the moment it is solved, putting the tEDBSyntaxMemo into a tGroupbox
with doublebuffered set to FALSE.
