OK, I just realized we're not talking about a font cache in TFF but the font cache in the OS. Found some information at Macworld on how to clear those caches per user in Terminal. But I'm a little wary of doing it. Should I, or might it cause other problems not worth bringing on? Any different ideas about this Facebook text entry issue?
Can you describe the "crazy errors" happening when you enter text? I use FB every day and I haven't had much reason to complain other than text entry may be a bit slower than when typing in a word processor because FB is constantly looking for links and other things it can process during text entry.
Mainly cursor position. The cursor moves of its own accord, jumping back a few characters while I'm typing and inserting the characters where they don't belong.
Making matters much worse, I also frequently have trouble deleting things. The simple back-delete doesn't work. I have to highlight what I want to delete first and even that workaround sometimes has to be repeated. Maybe that is just another symptom of cursor position error, I don't know. It all seems to be more severe with the comment fields (smaller font) than with composition of original status posts.
Sometimes, even when I have corrected something that got screwed up, and the word or phrase looks correct on the screen, TFF still thinks it has typos and puts the red spell-check dots under it. I ignore this at my peril. Usually when the text is posted it turns out it IS still screwed up, most often by character spaces that were not visible in preview.
I tried switching keyboards a while back, didn't help. Oh, in case anyone wondered, I did do the "refresh TFF" thing, as well.
I've been on FB for a bit today and written several comments without any interference at all. And it's Sunday, which normally is NOT a good day on FB. Go figure. Hoping 38.3 is going to work out better for me than I thought.
P.S., I'm beginning to wonder if this is actually a static electricity problem, as I have been seeing other evidence of static being an issue on/around my desk. So that's the next thing I'm going to tackle.
Good to hear your Facebook experience has improved. Did you clear the font cache? This would be a useful information for other users. BTW I doubt static electricity is to blame in this case. It can damage the RAM chips and other parts of your computer, but then you'll start seeing much more severe problems.
You're right Chris, the static idea was a senior moment on my part :D . After all, if static were the culprit it would affect all my typing on the Web, not just on FB, and presumably in other apps, too.
The FB performance did start to degrade toward the end of my session, with the cursor jumping again. :(
