Webhelp gives "Unable to get property 'toUpperCase'" on search after using the Webhelp to CHM tool
Note: I waffled between putting this in this forum or the chm forum... went here because it only happens when I convert a webhelp to chm.
I emailed support and talked to them via IM. Never ever received a response via email, and the IM support person said they would call me by eod and never did. (side question, why is support so unsupportive these days?)
RoboHelp Classic 19. Patched all the way up.
I built a web help using an existing template modified to our color scheme and icons. Everything worked fine.
I then used the Webhelp to CHM Conversion tool. Everything seemed to work fine, but clicking search gives this "Unable to get property 'toUpperCase' of undefined or null reference. It tells me which line the error happens on and which character. This error is a showstopper, as no matter which option I select, the search DOES NOT WORK.

I tried the same thing with every single skin available, same error.
I tried one of the sample files, same error.
This is apparently a known issue, I see it in the forum but none have an answer. I know that the problem is in the code, probably in the referenced file. Why this issue still exists when I see other posts in previous versions of RoboHelp is astounding. (Pardon me, I'm extremely frustrated that I have to post here because support has ignored me.)
Has anyone ever successfully fixed this error on their own? Is there an adobe developer chillin' in the wings that knows what the problem is and can fix it? We release in 3 weeks and I cannot send help out with a non-functional search!
