Removing Files w/ MultiFile causing IE8 App Crash

dougm
Hi Dean, I'm experiencing IE8 crashing when removing a file from a mulitFile list. If I set IE8 to compatibility view (compatibility view enabled - now IE8 runs in IE7 mode) there is no problem. I've included my environment below with the App Crash logs for each time it crashed. I don't get why the time stamps on each App Crash log entry are the same - these span over the course of 2 days. Looks as though mshtml.dll in IE8 takes a dump when trying to remove the file.

Windows Vista Build 6002 SP2

IE 8 .0.6001.18865 w/ Flash PlugIn 10.0.42.34

Win2003 Server

IIS 6.0

.Net 2.0 Framework

MultiFile tag: Upload:MultiFile ID="MultiFile1" UseFlashIfAvailable="true" runat="server" /Upload:MultiFile

Not contained in Update Panel - although there is an update panel elsewhere in the page.

If I remove UseFlashIfAvailable="true" the crash still happens. In either case I'm not getting any JavaScript errors.

NeatUpload version 1.3.20

Hi Dean,
I forgot to mention that when using other browsers (specifically FF3.5.7 and Chrome3.0.195.38) the multiFile works fine.

Thanks again.

Does the problem occur on the demo page on this site?  Does it occur everytime?

FYI, I can't seem to reproduce the problem here with a nearly identical setup, so I suspect you are running into a bug in mshtml that just happens to be triggered on your particular page when you delete a file. 

If you can't reproduce in the demo page on this site, can you reproduce the problem if you configure NeatUpload-1.3.20/dotnet/app as a web application and then view NeatUpload-1.3.20/dotnet/app/Brettle.Web.NeatUpload/Demo.aspx?

Hi Dean, On your Demo page - I can reproduce the problem fairly consistently. Out of 6 tries - IE8 crashed 5 times. Out of 4 tries in compatibility mode, it never crashed. I've search around and have seen mshtml.dll patches - but haven't investigated that thouroughly. I'll try your other suggestion regarding configuring dotnet/app as application to see what happens then. Thanks again.

Hi Dean, I again was able to reproduce the problem when configure NeatUpload-1.3.20/dotnet/app as a web application. However, my problem is solved. Others using IE8 w/flash plug-in have posted similar problems where mshtml.dll and flash (versions 8x and up) were butting heads. Even if you DISABLE the flash plug-in, it will not fix the problem. You have to go to Control Panel, Programs and Features and uninstall the flash plug-in. Then go to flash.com to get prompted to re-install it. Basically an unstable Flash plug-in installation can trip up the mshtml.dll file - with the flash plug-in enabled or disabled in your browser. Hope this helps others that have had this same problem. Thanks again.
