Zeus IDE

When I scroll any document rapidly with the mouse wheel, the scrolling speed is normal at first then slows dramatically. The my CPU usage spikes upwards of 100% when this is happening. I have a relatively new, powerful PC so I am not quite sure what would cause this. Any thoughts?

Which version of Zeus are you running

There was a problem in the way Zeus was handling the mouse scrolling event, which caused symptoms similar to those you describe.

This bug dated back to when the scrolling feature was first added, some five or six version earlier, but it should have been fixed in the more recent versions.

I ran a test in the latest 3.94a version and it seemed to be working fine.

I am running 3.94a.

WinXP SP2
Pentium M 1.7GHz
1.0 GB RAM

The CPU usage goes up noticeably when I scroll by any means (up/down, page up/down, scrollbar, etc) but is really bad and has a noticable lag when I use the mouse wheel.

Could it be a Pentium M thing?

If I scroll the wheel as fast as possible I can get the cursor to scroll about 100-150 lines in about two to three seconds.

During the scrolling I can get the CPU usage to peak at about 45-50%, but I don't notice any slow down in scrolling

In comparison how many lines does you mouse wheel scroll in a similar period

I had a look at the mouse wheel scrolling code and I think it might be possible further optimize the scrolling

If this is the case the wheel mouse scrolling should be faster in the next Zeus release

This bug should now be fixed in the latest Zeus for Windows release.

I downloaded the most recent version about a week ago and am running ZeusEdit on Windows XP Pro x64 on an MSI motherboard. No matter what value I set the Control Panel Mouse-lines-to-skip-on-wheel-tick to it only scrolls one line at a time.

This bug will be fixed in the next patch, due in the next month or two.

This bug should be fixed in the latest Zeus patch.
