This may be an off-the-wall question but I googled and got no hits on my issue. All of a sudden, I no longer have the option to choose the "edit sheet" function within a drawing by right clicking on the blank area of sheet. I had this option for years and it was convenient. It no longer appears on dialog box. Conversely, I still have this option on the left column where the sheets are displayed. From there, I can still right click on the sheet and now have to choose "edit sheet" from there. Strange thing is that once I'm done editing my title block, etc. I can now choose "edit sheet format" to get back into the drawing views. Any ideas are appreciated!
no option when RMB outside of views area:
Can find from left column though:
