Citrix ICA problems…

I have a remote client trying to connect to a Citrix 1.8 server. About every other time we launch the ICA, either the session freezes up when client is trying to print OR we get a wfica32 dialogue box error when initially launching the client. Theapplication only works as desired about 1/3 to 1/4 of the time. The client is loaded on a w95 system connecting via a dial-up. Thanks for any help.
