LayOut Tray Tab Issue

This started happening about a week ago and I’ve tested two different mouse controllers. When I click on a tab in the tray or an item like linetype the tab jumps upward. I keep my scrapbook at the bottom and now it’s almost at the top. When I click on a layer type to change it, that layer jumps to the bottom of the list.
Very frustrating, I’ve shut down all programs to restart my computer but it’s still happening.
I hope this post is designed to be read my a moderator or someone that can help.

What version of SketchUp/LayOut are you using? What operating system? What graphics card? Please complete your profile with this information. It’s useful for helping you.

NVIDIA GeForce GTX 1080

This just started happening however. Been using this computer for about 8 or 9 months.

I just created a new tray and fixed it to the screen. So far so good. Unless you are aware of a separate know issue that I’ll keep working with and see if that worked.

Is the default tray disconnected from the main window?

When you installed SketchUp did you do it correctly? That is, did you right click on the installer file you downloaded and choose Run as administrator?

It has been for years. I moved it and just figured how to get it back into it’s fixed position. It never bother me before until it start bouncing my tabs around.
