I'm encountering a strange glitch and can't seem to find a fix.

One specific subassembly in my drawing refuses to 'take' a balloon. When starting the balloon command and selecting any edge or face on the affected subassy, the cursor moves as if a balloon was placed but no balloon shows. When clicking a second time, it brings me back to the balloon command.

I've tried the following usual solutions to no avail:

• Deleting/re-adding the view and trying on any other view
• Changing the display style between shaded/wireframe/etc.
• Changing configurations in the BOM and top level assembly
• Auto-ballooning the view (all appear but the one balloon I need)
• Creating a new drawing file
• Rebuilding drawing & assembly
• Reloading subassy in top level assy
• Restarting Solidworks
• Restarting computer

Any ideas?
