sjordi 39 Posted March 2, 2021 (edited) Hi, Just designed test app which is mainly using a TTabControl with 7 tabs. Several TLayouts (some inside other layouts) on the first two tabs When I try to add any of the form factors then the IDE crashes and states the following message (attached) If I start a blank app and immediately add the form factors, then paste the entire structure of my app into the main form, it works, but it is crawling, very very slow. Any idea what could cause such a thing? FMX app in Delphi 10.4.2 Thanks for any light Steve idecrash.txt Edited March 2, 2021 by sjordi Share this post Link to post

sjordi 39 Posted March 3, 2021 I can't as it uses 3rd party components. But I nailed the problem. It's a TMS Component. I started from a blank form and added all my components one by one, adding/deleting a form factor each time. Then I noticed that the problem is the FMXPlanner (calendar). It works fine as long as you don't set either the right and/or bottom anchors. If you align it to anything, then it crashes. If you set Align=None and you remove the bottom/right anchors, you can add any form factor you want. Just wrote to TMSSoftware to find why. Thanks for your input. Share this post Link to post
