Thunking problems with Win95 OSR2

Hello,
        Has any one experienced problems when calling QT_Thunk under the
new Windows95 OSR2? It seems to not do anything. My program does not
crash at all. The calls when thunking are just silent. What has changed
with the new OS version? How can something that worked in the previous
version be written so that I works with both the older and new OSR2
versions? If anyone has any suggestions, pointer or answers I would
greatly appreciate it.

Thank you.
