Hello, I am not familiar with the pros and cons of FSUIPC, I just use the Buttons and Switches facility. Today 27.5.2012 I purchased the registered copy of FSUIPC v4.82 and opened FSX. I loaded the PMDG 737ng (default) with the purpose of setting buttons etc. In past versions when clicking the aircraft profile box it automatically loaded the selected aircraft in top section, however today a box appeared and asked which aircraft I wanted to use, or words to that effect, and I entered PMDG 737NG. Will I have to do this each time I load this aircraft with different liveries etc. I hope you can help me with this situation. richard welsh.
