In the process of replacing or adding gauges in aircraft panels, I have been unsuccessful in the installation of default FSX gauges, yet the same gauge by identification from FS9 seems to work fine.
For example, I like to have a timer in my panels. I have always used the Dreamfleet timer, but unfortunately, it is of FS98 origin and is not acceptable. I just disabled the clock in the FSD Navajo Panther panel, and substituted the timer that is in the FS9 Extra Default Panel. No problem. But if I try and put the timer from the FSX Extra in by the same procedure, it never shows up.
No biggy, but I am curious. Anybody know the solution to this, or why it is this way?
