I'm a 25-year veteran of InDesign operating CS5.5 in Windows. Suddenly, I'm unable to move panels. I've trashed preferences, but attempts to move panels are halting at best and I'm unable to resize by grabbing the corner handles. Any help would be deeply appreciated because I'm in the middle of designing two book projects. Thanks!
What operating system are you using?
CS5.5 is supported on:
Windows10 64 bit. I've been using it with no issues for more than a year.
