UR Hangs With 99% CPU Usage

[cnewtonne]

UR started hanging on me as I was working today with ultrarecall.exe at 99% usage. It is doing it consistently when I switch to an item of text type that has a table in it. As long as I do not open this item, UR is fine. It has done 6 times so far.

To investigate the issue, I turned off 'check spelling as you type' and here is UR behaving itself. No hangs no more. The minute I turn on this feature, it locks again at this high CPU usage.

My inquires are:
1) is this a known issue?
2) I turned live spelling check off for now, but how can I fix or wordaround the issue and use spell check?
3) I'm open to work with you on this issue. Just le me know what further information you need.

The spell checking component used by UR chokes on Chinese (and possibly other Unicode) characters. There is not currently a solution, other than disabling active spell checking, for viewing/editing text items with such characters.

This is straight US English. Nothing fancy, no special characters or ohter langs used.

Please copy the problem item to a new database and ZIP and post/send it. Thanks.

I just did (to the support address).

It works ok here. Try closing UR and deleting riched20.dll from the installation path.

I have replaced the current riched20.dll 12.0.4017.1003 with RICHED20.DLL version 5.50.99.2010. The issue no longer occurs. I tried same scenario but could not get UR to hang. So I guess, this should resolve the issue.

Thanks for the follow-up.
