windows vst~ bug/issue

Hi-
I have found a problem with the vst~ object on Windows. When dragging a vst plugin into a patcher in edit mode, it doesn't create an interface to the vst plugin as it would on Mac. When I do drag a vst file in it tells me 'file not found' The plugins I am using are mda vst plugins, which have a .dll extension. I tried removing whitespace from the name with the same result. However, I did find a work around:

-In order for the plug-in to work you need to remove any spaces in the name (mda plugins all have a space int he name).
- Open the patch
- in the patch there is a vst~ object with a message box that tells the object to load the vst plugin - attached to a loadbang.
- to use a different plugin, change the name after the message plug to the name of you plug-in (remember to remove whitespace, also make sure the plug-in is in the search path [i.e. the same folder])
- then reload the patch
- resize the vst window

Seems like this should work the same as on mac however-

thanks-
