I'm not asking you to program. I'm asking you to play "logical deduction." Try turning one thing off at a time until you find a match. Very simple rules. Instead, you have come to the forum and posted publicly: "I do not know but," "I feel" "there is a compability problem with Gizmo." You do not know, but based on your simple gut feeling, you assume that Gizmo is the problem. You take the problem public without doing ANY work to further test and refine your assumptions. You are being lazy. I will freely admit Gizmo has its share of issues. See above for details. Additionally, you haven't shared the version number of Gizmo you're using. Further frustration ensues. If you're using Gizmo 10.x some of the very late versions will cut power FOR DRM products NOT ACTIVATED. The following assumes that you're using Gizmo 11.x. There is no reason for Gizmo to "suddenly zero your mixtures". Why would it do that Tom? Please explain what I might have been thinking when I put that in. What made you assume that I would want to put such a thing in? When Gizmo clashes with SASL or plugins that use sound it is generally a catastrophic failure. The sounds play corrupted. The sim crashes. There is no known clash where Gizmo sneakily waits until you're in a climb under auto pilot command and then yanks only your fuel mixture, just for a laugh. Had you added the simple words; "..because this drives me crazy, I have even tested a UFMC clibm without gizmo installed at all, and it doesnt happen anymore, therefor PROVING that gizmo is the problem" this conversation would go very differently. As is, you are behaving like a lazy irrational customer who just wants to bitch. As a finishing note, thank you for donating to the project, you have helped Gizmo grow so that thousands of people can enjoy X-Plane to a new level. I continue to work hard every day like all the other X-Plane Developers so that we can bring you more stuff to use with the hope of some day making nice return on our work, be it financial or otherwise. Personally I see great satisfaction in someone going from "bare bones X-Plane" to "look at all the crazy stuff I can do with Gizmo.." in about two days on average. I hope that in future other people will be encouraged to donate as you have done. I feel that the number of takers vs care-takers isn't high enough, so I've stuck a nagware in. It's still entirely free to try out, use, reship, and make derivatives of, something you won't find in many other products for X-Plane. Good day.
