Am attempting my first upgrade of an aircraft not included with 6.xx, the X-1. Have a panel bitmap ready to use for the cockpit but have been unable to delete undesirable gauges. Am able to drag and drop gauges on to the panel but haven't figured out how to delete them.

My System:
P4 1.6ghz
384mb RAM
WinXP
nvidia geforce2 64mb AGP latest drivers
