Have you ensured RoboHelp has the latest service release applied? To my knowledge it should reflect 18.104.22.1684.
Beyond that, I'd suggest opening one of the sample projects or creating a totally fresh project and see if this happens with a different project open. I can't fathom why that would make a difference, but it's worth trying.
Yes, I verified I have the latest update shown in your image - "22.214.171.1244".
I did open the sample project "EmployeeCare3" and of course I had to upgrade it before it would open. After upgrading, it too locks up when I make any adjustments to the pane width.
I meant to add this to my last post...
I even tried deleting the !ScreenLayout!.fpj file from the !ScreenLayout! folder and the rhscreenlayout.apj file just in case one or both were corrupted in some way but no luck.
I think I found the solution after some experimenting...
The screen layout I had, had three pod panes stacked on top of each other. The Project Manager pod was pinned above the Output Setup pod which in turn was pinned above the User Defined Variables pod.
When I clicked the Auto Hide button on the UDV pod to remove it from the pinned state to the auto hide state, leaving only the Project Manager and Output Setup pods stacked, I was able to resize the pane width without RH locking up.
Apparently, stacking panes more than two high doesn't play nice with RH.
It would be interesting if someone else running RH2015 can try that screen layout to see if you too experience this locking up issue.
Thanks for troubleshooting the issue this far.
We are also trying to replicate the same at our and and will come up with a fix in case this is a bug.

We have reproduced this issue at our end.
It happens when any pod is docked vertically side by side to the pods you have mentioned.
From the image you have shared, if you close the TOC pod then it will work fine.
Thanks for helping in investigating the issue.Please log a bug at Home and we will take it forward from there.
By logging the bug to bugbase you will be able to track it.
Thank you Surbhi,
I created a bug as requested.
I tested it also where if you close (or Auto Hide) one of the three stacked pods - leaving the TOC pod intact - RH does not lock up.
