RCV3 and FDC

Hi:I am trying to use both combinations above, making sure I start RCV3 first then FDC, but I am having a lot of problems.The first is that in ADV display, when I hit 1 to get my ATC the message on the ADV display keep running like crazy repeating itself, and it is kind of blocking or freezing FS2K2 to do anything meanwhile. EXP: punching numbers on the heading or level of the panel.However the sound is clear and very normal for RCV3 and FDC which make me think that every thing is running properly at the background, but it kind of take a long time to respond.What I was using is Posky B767-200 + PIC panel + RCV3 + FDC.I made sure that all other programs are close at the background.If any wave is playing, I cannot do anything with the panel at all, nor I can choose any other option from RCV, but after the wav is finished (RCV or FDC) it takes like a minute to respond again.I Have a P4 1.8Ghz with 512 Ram of mem, Sound Blaster creative Audigy and Win XP pro.Does this combination is OK or it is too much together.Any help will be appreciated
