help, doc commands very slow

Hi, I can't put my finger on why it's doing this, but since a few days help takes a lot of time to show. Either inline (selecting a function, selecting "help for", or by using the commands doc or help. The command "doc cmdname" takes about 10 seconds to show the help window. I did, taking fwrite as example, try "profile on;doc fwrite;profile viewer" and digging through the rabbit hole I arrived on a private java matlab method which is taking forever:

>> tic;com.mathworks.mlwidgets.help.HelpUtils.getDocCommandArg('matlab\fwrite', true);toc Elapsed time is 9.993832 seconds.

Any idea what could be causing that issue ? It also happens in safe mode, with no other running programs than matlab. I'd try a complete reinstall of matlab, but if I could avoid that that'd be great Thanks for your help

I am having similar problems with help in 2012b, but only in the last week. 'Help on selection' from a right click works but takes 10-15 seconds to appear. Searching within the help window doesn't work at all, displaying 'An error occurred searching the documentation' after around 10 seconds. Browsing through the help via the internal links works fine so it appears that it's something in the search mechanism that is at fault.

Running your tests above give similar results to yours. I've tried disabling the antivirus software and that made no perceivable difference.

Did you find a solution to this? Having recently upgraded all the way from R12.1 the help documentation is, as the name infers, helpful!
