Questions on Dimensioning issues and sketching in

Greetings,

Does anyone have the following poblems?

My dimension colors turn yellow, then are useless after that.  When I sketch on a drawing view, my construction lines appear to grey-out and are barely visible.

Pop-ups when putting in dimension do not pop up when needed.

These problems happen only sometimes on some drawings.  I usually have to delete the drawing and start it over from scratch.  We use Pro-e here also and I never had those issues before using Solidworks.  I have an HP Z400 workstation with a Xenon Processor running windows 7

Thanks in advance

Nick
