stuttering problem in winuae 1.2 with ClassicWB_ADVSP

hi guys,
im new to this forum, first up great forum over here,greetings to all amiga nerds.

ive got one problem:

i have installed the ClassicWB_ADVSP installation everything works fine!
now when i add a folder from my pc , i can see it on my amiga workbench

now the problems:

i cant copy from this added pc folder in winuae (workbench) everytime i want to drag and drop i.e. a whdload game folder , winuae crashes or i get the red reboot error

another thing is when i start a game from this pc folder that is recognized as DH1: oin my Workbench , the game failes to load or when it loads it stutters like hell,so its unplayable (the mouse is constnatly freezing) how can i copy folders from added PC harddrives to my system workbench drive in workbench( winuae-ClassicWB_ADVSP) ? i always get an error (volume is not validated when i want to copy from dh1(pc) to dho(system)

would be great if someone could help me!

think i found the prob , have installed amisys and put it in fullscreen now the games work ;-) no stuttering anymore or freezing

seems that window mode did some probz
