Editing a .c file fails when // comment is edited

[mike-jensen-sw]

Apache NetBeans version

Apache NetBeans 24

What happened

When editing a .c file, if I move my cursor to a // commented section of code, I stop seeing the text I'm typing. I the editor thinks it's doing things, as the file name goes bold indicating unsaved changes but the text I typed does not appear. The cursor still moves via arrow keys or mouse clicks, just no text appearing when typing.

Seems to be intermittent, several close/open of NetBeans and the problem was there, several it wasn't. Unable to determine a pattern.

Language / Project Type / NetBeans Component

How to reproduce

Open existing .c file, type // and further text doesn't show.

Not reproducible on a recent build. Please provide the message.log for the IDE run when this happens. The file is located in the user directory (see Help -> About) in the folder var/log. Please also test NB 25 RC1 (#8186), which contains an update textmate interpreter.
