[solved] Slow running program

JSHUK · Post by **JSHUK** » Mon Nov 30, 2015 12:40 pm

I recently upgraded to version 3.12.3 pro from 3.12.1 pro and immediately experienced problems with the program running very slowly. For example, something as simple as drawing a line would go something like this:

select the line tool and click on the position of the first point
move mouse to position second point
wait about 2- 3 seconds while the cursor "catches up" with the mouse position
click the second point.

I've tried uninstalling the program and re-installing, even into a new directory, with no improvement. Eventually, I re-installed ver. 3.12.1 pro to regain the usability. I'm not overly concerned about the fact that I don't have the latest version, but I was wondering if I'd missed something vital in the upgrade.
I'm using Windows 7 professional with all the latest updates, on a 32-bit machine. OK, it's old, (10 years +), but everything else works well enough for my needs.

Thanks for your report. Is that with a particular drawing or with an empty drawing? In the first case, please attach the drawing file (DXF,DWG). Thanks.

Hi, Andrew,
It was happening with empty files as well as a drawing already started in an earlier version. I can't replicate it now, of course, because I've reverted to 3.12.1.
I've attached a file that was affected. It does contain a number of block items which, in turn are made up from numerous complex objects. Perhaps they are slowing things down, although I didn't experience the delay with earlier versions.
I should also add that I have installed 3.12.3 on my laptop (Linux mint 17 32-bit) and that doesn't have the same lagging problem as far as I can tell.

Regards,
John

Just for fun, I've re-installed 3.12.3 onto a separate hard drive where I store all my DXF files and other stuff and I'm delighted to tell you that it seems to be working perfectly. So, don't waste any time trying to find a solution to a problem that probably doesn't exist! It was most likely finger trouble on my part!
Thanks for taking the trouble to reply.
Regards,
John
P.S. If it DOES happen again, I'll let you know.

OK, thanks for letting me know.

Just to let you know - it's happening again! Having delved deeper, I think it may be connected to the Bug report FS#1315, due to be addressed in the next release, so I'll see what happens when that comes out. At least, now that I'm aware of the situation, I can make allowances.

Thanks. I can confirm that this is caused by FS#1315 and has been fixed for the next release.

An update (QCAD 3.12.4) is now available.

Thanks, Andrew. I'm downloading it as I type this. Fingers crossed!

Now had a chance to play around with 3.12.4 and as you say, Andrew, it seems that has cleared that problem. Thanks.
