We've been experiencing similar strange behavior due to some Microsoft Windows updates. We're actively looking into it and will have a fix shortly. In the meantime, the issue can be circumvented by pressing the SMART ARRANGE button in the Workspace tab

Thanks for the quick reply and work-around

No prob Thanks for becoming a pro member! Much appreciated - we'll have an update for you soon with a fix for this

Thanks

I do see this error appearing recently, not sure if it related, boutght thought better leave a copy, maybe it helps

@DJ, we've been struggling with this problem for years. We've discussed it in the past many times. It's an ongoing issue. I've been having this happen forever and have gotten in the habit of just doing a Smart Arrange everytime it happens. That's all well and good but with a large project I arrange my controls a certain way to easily find them. A Smart Arrange jumbled them up. What a mess! In your defence you have tried several fixes in the past that didn't work.

I've got a large project with all three virtual screens filled and extending down and off the screen. It seems that this issue starts when controls start to over fill the workspace and scroll bars are added. In addition to that, I notice an oddity when I move from one virtual desktop to another anter making changes or moving controls around. I notice the small icon showing the desktops at the top of the page won't alway refresh and show the changes. If the change of any curtin desktop has not happened in the little icon and the ARC is closed, the next time ARC is opened controls are slid up under the menu bar like the OP shows.

I haven't pursued a fix for this in a long time because I got tired of hoping for a fix. Also till now ARC was free and it's hard to push for something to get resolved when you are not paying for it. LOL. 

It's strange that I can't reproduce it. It would be easy to fix if i could merely experience the same thing. Can you describe a step-by-step way to reproduce it? If you do, i can fix it. I can fix anything that i can reproduce

Hmm I spent (ugh wasted) hours this morning on three different computers and I can not reproduce this. I’m losing my mind lol - please if you can provide a video or anything that gives me a way to reproduce it?

Hi DJ, I'll get this for you asap. I've able to reproduce this strange behavior fairly often. Hopefully Murphy "opposite" Law won't bite me in the bumm now. LOL

Relax till then. Not a huge game changer. IT's something I've learned to live with. Thanks for the effort so far and sorry for your waisted time.
