insertion point glitch

[Timothy Miller]

Hi, I do a fair amount of tedious data entry with my liveCode stacks.

Now and then, a field's focus border is hilited, the cursor insertion point is blinking in the field, but the field is unresponsive to keyboard input. Clicking again in the field does not make a difference. The only way to make the field responsive is to click in another field, then click again on the field I want to type into.

This seems to happen inconsistently. Maybe 20% of the time. it happens in various fields, and in at least two rather different stacks. It can happen when I manually click on a field, or when a script places the insertion point in the field. It can happen with an empty field, or in a field that contains some default value, and whether I have single-clicked or double-clicked on a word in the field. I have never been able to figure out how to reproduce the problem. It's a minor annoyance, but if I do a lot of data entry, it can happen many times in a day, until I get sick of it, and try to figure out why it happens.

I've not been able to troubleshoot very well because the message box removes the insertion point from the field and terminates the glitch.

I have noticed that when a field is unresponsive to data entry, it is also unresponsive to tabkey and returnkey (tab on return is set to true). Autohilite is true. List behavior is false. Traversalon and showFocusBorder are true. sharedText is false. The fields in question have no scripts.

Is this a known problem? Is there something I can to do make it stop? Lacking that, troubleshooting suggestions would be appreciated.

It's been going on through many updates of LiveCode, possibly for several years. This is LC version 5.5. It happens both with my MacMini, running the current Mac OS, or my old laptop, running OS 10.6.8.

Thanks in advance,
