On our Win Srv 2012R2 RDS session host server (terminal server) I have bad problem. Office 2013 documents with Czech spell checking lags (1-2 min) when I close and save document. When I change spell checking on English everything works OK. On Windows 8.1 works OK both spell checking.
I tried to investigate with process explorer, and when winword.exe lags, active thread is wwlib.dll!DllGetClassObject with Stack:
KERNELBASE.dll!ReadFile+0x3
MSGR2CZ.DLL!GramGetError+0x3ffeb

MSGR2CZ.DLL is Czech language checker.
Any idea?
