Hello [name]! Thanks for joining the GMC. Before making any posts in the Tech Support forum, can we suggest you read the forum rules? These are simple guidelines that we ask you to follow so that you can get the best help possible for your issue.
Please report all bugs through the proper channels, and include links to test projects that demonstrate the issue, if required or possible. You can easily file a bug through the Help Menu in GameMaker, selecting the "Report a Bug" option. The forums are not checked by the YYG devs, and even if they were, unless a bug is filed through official channels, it won't be considered for fixing.
