After installing the RTM version of IE10 for Windows 7 (10.0.9200.15521) on a couple of workstations here, I noticed during testing on theIE testdrive site that the new spellcheck feature didn't work for any domain user, but worked fine for local users. I have narrowed down the cause to our use of Folder Redirection
for the AppData directory.
Another symptom is that when I go to Manage Add-Ons>
Spelling Correction, the Enable spelling correction box initially shows as ticked. However, when I click on any individual language, this is what greets me:
For unaffected users, the box is ticked for every language, and the blank button on the right reads 'Set as default'. For affected users, the button is not only unlabelled as shown, but seems to have no functional effect. If I tick the box and clickClose, then go back in, it shows as unticked again.
The actual location that AppData is redirected to appears to have no effect on the problem, only that it is a UNC path. I've tried giving the user Full Control (and even exclusive permissions) to the folder with no effect, and it doesn't matter if the path is a DFS path or not. I have also established that redirecting to local path on the workstation (e.g.C:\TestAppData) does not cause the spellcheck to break, but redirecting to thesame location when referred to as a UNC path (e.g. \\localhost\c$\TestAppData)does cause the problem.
Folder Redirection is quite common in UK educational institutions as one method of keeping down the size of roaming profiles, but so far I've only been able to contact 1 other institution that is testing IE10 on Windows 7, probably due to it only recently
being released, and not yet being available on WSUS. However, they have reproduced the problem, reducing the likelihood that it's something specific to our setup. I'd be interested to hear reports from anyone who can (or cannot) reproduce this.
Who should I be contacting about this? We have Software Assurance as a last resort, but I'm loathe to use up one of our PSS entitlements for what seems like a straightforward, reproducible bug.
