Winbox / redirected Application Data folder

Just emailed support, but I figured I’d ask here as well in case anyone has run across this.

I’m on a Windows domain where profiles are kept entirely on the network, GPO pushes folder redirection rules that also redirect the App Data folder to a network location. Winbox shows the loader screen fine, but when you connect to a router there’s a 20-40 second break where the loader screen is unresponsive and appears to hang while the cached DLLs in the app data folder are accessed. Eventually it connects and from then on everything works fine.

Does anyone know how to get around that limitation? 20-40 seconds doesn’t sound like much, but we connect to lots of routers many times during the day, and it becomes aggravating after a while.
