Hi Rob - is this a large file? If so, can you see if other large files behave similarly? I ask because your system seems a little low on RAM - I have no idea if this could get in the way of drawing - but just checking.


No problem with large files this one is small 6mb we work with files 50md to 80mb no problem, it is just this file that acts strange

Hi Rob - can you send us this file?, or upload to my attention via (SaveSmall and zip is best)



I do Pascal THanks

Hi Rob - thanks, I see the problem here as well when zooming in and out with the mouse wheel. I’ve added your file to an existing bug report that I believe is related,


Ok Pascal Thanks lets see what is coming out of that file grts
