Changing from a Workspace to another is very slow (?)

Hello

Whenever im changing workspaces , let's say from Assembly to Color for example

it takes an unsual amout of time in doing so, more than 10 seconds sometimes

and its really slowing down my workflow as you can imagine. Any thoughts or

solutins on this?

Thanks in advance
