Glitch? Workspace windows won't open

[TM4926]

Hi all,
I don't know if anyone else has had this issue before. Recently, I get this bug where whenever I open a workspace window (either by recalling a workspace on the side or opening a workspace window through the softkeys) they immediately (<1sec) close. This is only remedied by restarting my laptop, and occurs mid-show

Is there a solution?
Many thanks!
