Hello .... I'm sorry for bothering you. I know I must be missing something that is probably pretty obvious, since no one else has asked about it. I did look through these forums and searched them also but I can't find how you switch the tanks. Also, I don't understand how they are both set to external tanks and when I drop both tanks the right side engine continues to run.  
 
I've noticed that when using any of the p-38's, at times, my graphics become very choppy. Sometimes I also get like flashing, it's just like the graphics just aren't right. I have checked the fps when this is happening and it doesn't seem like it matters. It happens sometimes with high fps and sometimes with lower fps. Has anyone else complained about this?  
 
I'm running FSX on Windows 7 64bit. Intel 6600@3.1ghz. 4 Gb of ram. 8800gt/1gb. Thank you for your help.
 
 
 

Thanks Jessie for getting back so quickly. I did left click but didn't right click, so I'll try that, thanks. The drop tanks aren't a problem I get them to drop. I was just wondering why the right side engine continued to run after dropping both tanks and the selector set to externals.
