Excel COM, Possible 98 issue

[bshoenhair]

Since COM was last updated to get rid of Excel memory bug I have been getting a fatal Excel error when the script closes.

Can someone please verify this probable issue in Win98 ?

Win98 = ERROR

WinXP = No Issues

Note must be AutoIt Beta 3.1.1.4 or greater

This is the error:

Hello,

The FOR..IN loop is broken somehow (without even touching it :-) .

I got also a report about a FOR..IN loop issue from Valik, I have to ask him if that's the same problem.

I can reproduce the problem. It disappears when I leave out the two FOR..IN loops.

Very odd that it only shows up in Windows 98..

But I will look into it!

Thanks for testing the beta ! :-)

Regards,

I isolated this problem in the AutoIT COM code.

In the FOR..IN loop, some references to objects are not released. After quitting Excel, the EXCEL.EXE tries to release them anyways and crashes doing so.

I fixed this one, together with some other issues.

The fix will be included in the next beta version of AutoIt.

Regards,

Wonderful, can't wait for next Beta release.
