Layout is acting strange

Is anyone else having issues with Layout doing strange things?

Running very slow
pages rearranging on their own - everytime I go to any page to make a change it puts in as page 1

I have already shut down several time and reopened. I have had this happen two different files.

Have you tried to repair the installation?

Download the latest (2018) version installer, rightclick on it and choose ‘Run as Administrator’
When prompted, choose repair

ok I am doing as you instructed. However, I have been using SU 2019 since it’s release last year. Would I not want to repair 2019?

Yes you would. You would also want to update your profile which indicates you are using SketchUp 2018 to avoid confusion.

Was not aware I would need to do that with each update I install, thanks for the heads up.

I have now repaired both 2018 & 2019 and now layout will not open at all.

I re-booted and so far things seem to be running smoothly. Thank you again for the help.
