Intermittent problem with modification dialog box not appearing on screen

Microstation V8i sp3

I am experiencing an intermittent problem with the small editing dialog not appearing when a function is initiated such as; "copy parallel", "copy", "change attributes", etc.  I am not able to enter the proper data for the edit such as a distance.  When this happens I am having to close out the file and reopen it to get the dialog box back.
