Frequent crashing when editting dxf's??

[tgm]

I have been experiencing way too frequent crashing of VW11 while trying to edit imported AutoCad files.

I import the file and during editting, removing text, objects not required etc.,I frequently have the program 'lock up', where the cursor will not operate, nothing works and then I get the dreaded 'Program not resonding' message.

This only seems to happen on imported dxf and dwg files. I have not imported any other file types.

I even had it happen last night on a new layer of an imported file with no imported data on the layer.

Any thoughts??
