myBalsamic.com issue : occasional loss of text edit; have to logout?

[orangeleafjames]

We are occasionally finding that we cannot type into any new controls text - so if we add a Label or String, the text cannot be typed (or overtyped)

the text can be deleted

Mac OSX, Firefox

if we logout and login (this may be unrelated) … or wait for a few minutes and try again, then the text can be edited

Hi. Have you tried in another browser to see if the problem persists?

I can’t reproduce this on the latest version of Firefox here, so it will help to narrow down the issue a little. Is there any pattern that appears to lead to the text being uneditable?
