Hi = Hi,

 

Whats the simplest way to = make the=20 content of the rich text box “selectable”. We have an awful = lot of log output=20 going to that window, all of which is needed. Ideally I’d like to = freeze the=20 window, select the text and have the RTPappender continue its writing. = By=20 default I’d temporarily set the RTB enabled =3D=3D false, select = the text and then=20 set it back to true but that seems a bit = luggish.

 

Any=20 tips?

 

Thanks
