After I downloaded the update yesterday, my stand-alone has a very high CPU usage. It continually switches between high 70's & high 40's every 1 second. I've tried everything .. restarting, cleaning out registry, etc. and nothing has worked. Any suggestions? Thank You!

Are you getting high CPU usage just when you started the app, or when you did something in it?

When I bring it up from the system tray it peaks. I'm not doing anything in the program.

Works fine for me. Seems like you have some kind of conflict within your Windows.
Try to uninstall the program, remove the installation folder in c:\program files\myibay, reboot your PC and install it again.

The only activity it does when you don't do anything is updating times. You can try to disable it in Settings - Interface - Auto Time update

I'll try to reinstall because I need accurate time. I'll follow up and let you know if it solves the problem.

Problem is still there. After reinstall I ran ccleaner to remove all traces on reg, rebooted, reinstalled. CPU 70's-90's now.

I meant after uninstall I ran ccleaner.

I see no need to run ccleaner every time. Maybe that caused the problem? I never had it installed on my Windows.

Can I reinstall the prior version and how would I do that?

Let me know if that helped.

Reinstalled prior version and problem is gone. So the new version has high CPU usage on my machine.

Just for my own curiosity, can you please try the following build:

Do you need me to uninstall and reboot first?

Good question. Just to make sure everything is clear, yes please.

A bit lower but still 56-63. In task manager it continually toggles back & forth with system idle every second. It doesn't do that with prior version.

Too bad I could not replicate it.
I tried some old XP 32-bit machine and newer Win 7 64-bit. No issues.
I'll see if I could find anything.

I had to uninstall setup2 because my mouse kept freezing. So I'm back to the prior version before update. Are there any issues with this I should be aware of?

If you want to privately see a "hijack this" scan of my system out of curiosity let me know. But if I'm the only one reporting the problem it's no big deal to use the old version. If you need my help at all just let me know!

Yes, you are the only one who reported it.
Funny thing, the other version "2" I gave you is just a different package, but the binary inside is exactly the same.

HijackThis will not show the correspondent information (dll conflicts and such) so it won't really help.
I'll investigate more and probably bother you again if that's okay.

That's very strange! No problem at all helping. My system is very secure because my business in online but I'm going to run a full malwarebytes scan unless you know of a better one.

This is not malware-related for sure. That's some kind of conflict with other dll's in your system which were installed by other software packages.
I always include the latest versions of everything, but if you had other application which came with older version of the same exact dll, then it may cause the issue.
