I haven't seen this issue before. Could you tell us a bit more about your XP environment? I'd like to repro the problem locally.
- Does the crash repro outside of the browser, in stand-alone apps?
- Is there any time when when you can set focus to a TextBox without crashing?
- What language version of XP are you running?
- Under Control Panel \ Regional and Language Options \ Languages \ Details, what do you see listed? What is your default language and what are the installed services?
- If you can catch this under a debugger, is there an inner exception?
- Is the TextBox customized in any way?
- Do you see this crash on any other machines?
Thanks for letting us know about the problem. If we can see this locally, we should be able to fix it.
