iOS Bug: Frame jump event

I am having a problem with a simple event that I think must be a bug in the iOS exporter. The event is:
IF user double clicks on a button
THEN jump to frame 20

Here is the link to the mfa. https://www.dropbox.com/s/l47fx04of2...rer%20game.mfa

The problem is on a frame entitled "Frame 1" (frame 4 in the application). If you look at the events in the group entitled Escape to Main Frame, you will see that double tapping the "menu" button should cause a jump to frame 20, but often it results in a jump to another frame (although this is not entirely consistent-- sometimes it does jump to 20, but only rarely). I believe the event in question is number 147, although I've done some work on the program so it may not be exactly 147 ((i'd check the mfa to find out but don't have access to MMF2 on this computer). There is no button located in the same place as the menu button on Frame 20 that could trigger this jump as a mistaken click through event. I have no idea why this would happen but it seems to be related to the fact that "FRAME 1" has a subapp. No other frames in the program have a subapp and they all handle this same event correctly.

The event works correctly in the exe and flash versions of the program.

Hi Brett,
Thanks for your file, I will investigate.

Hi Anders,
Do you have any ideas what is going on yet? Is it a bug? Thanks,
Brett

I can't reproduce this with your current file. Can you tell me which frames this happens from? I noticed that you have the 'Menu' object in several frames.

Hi Anders,
It happens on frame 4 (it is titled "Frame 1"). It is only a problem once you test it on the iPad device. It works fine otherwise.
In the game you can get there by clicking on "Recon" on the main menu. Then you will go through a couple more frames with animations of the ship entering the cell. Once inside, you can fly the ship around. This is the frame in question. If you tap the menu button, then double tap it to go back to the main menu (frame 20 I believe), it often jumps to a different frame. Please let me know if you experience this and what you think may be causing it. Thanks,
Brett

I always get to frame 20 when I test on my iPad no matter how many times I try.
A wild guess is that the problem isn't present in the production-version I am working with and that the bug will be fixed in the next beta.
If you want me to I can try it again with the XCode project that MMF2 currently exports.

Hi Anders,
This is strange because when I try it almost never jumps to the right frame. What version of MMF2 are you using? I have 257.1 currently. Would you mind trying it with the X code project that MMF2 exports? For me, instead of 20, it almost always jumps to frame 18 ("Story Entrance to cell"). Weird. Please let me know what you think. Thanks,
Brett
