As soon as I integrate the chart control into my app I have the same problem as in the samples, the mouse cursor is much slower.

I've set my mouse cursor speed to fast and as soon as an app with the Chart Pro is active it is slow. I activate an other window and the cursor is fast again.

Andre, does this mean you got a download for the release version?

No, I've downloaded the eval version because I expected the retail version to be available by now.

Can you guys reproduce this problem? I do not have this problem under Win2000 with a HP mouse but under WinXP with a Logitech mouse.

I use a Logitech mouse and tested with Win7 x64 and Win Xp 32and also don't see the problem.

Can you verify it is the mouse?  Maybe try another mouse on that machine?

As soon as I link to the Chart Pro lib (even without creating a chart) and start the app, the mouse cursor is slow.

If I then switch to any other app, the mouse is fast again. Back to the Chart app, slow.

What about the CJ ChartPro examples? Do they slow down the mouse cursor too, or is it just your own app?
Couldn't observe any slow down with the examples on a XP and Win7 machine so far.

Look in the debug output. Probably, some mouse hook dll is injected into your process (from mouse vendor). Perhaps some parts of the Chart package don't like sloppy written system-wide hooks?

We try to figure out what it is. I guess it is the bogus Logitech mouse "driver" (app). Without the app running the back/forward button and the task list button on they mouse doesn't work.

I can see in the debug output that it is loaded in my process.

Ok, it's the LogiTech MouseWare driver.

em_exec.exe (Logitech Events Handler Application) version 9.79.25.1
It loads "Logitech\Scrolling\LGMSGHK.DLL" (Logitech Message Hook Library) into each process.

So all older LogiTech mouses will be affected.
Newer ones use LogiTech SetPoint driver.

Try running the software as administrator under Vista+. Hooking fails :)
 
Or install a WH_DEBUG hook and make sure to somehow remove the WH_GETMESSAGE hook for the specific dll :)

The MouseWare driver only runs under 2000 and XP.

I could also just buy an other mouse. LOL
The problem is not that I need a solution for me, but we need a solution for all our customers.
