hi People, I don't know what to think to solve the current problem I got myself into! From the beginning... doing some tests with the "SetWindowPos(...)" MSWin-API function, I realized that my new forms created and called from the main form, using the "SHOW" procedure, were no longer being in the background!!! That is, the new forms are always in the foreground, regardless of whether or not the "FormStyle = fsStayOnTop" is set!!!! to clarify further: all new forms are "FormStyle=fsNormal"... ALL, either formMain, or a formSecond called in formMain! none of the form properties (at all) were changed, it's all default by Delphi. nothing nothing nothing is being changed The new VCL projects are creating forms always in TOPMOST after my tests with the function call "SetWindowPos(...)" that I made in a test project!!! After a moment of total madness (laughs), I tried checking the Embarcadero Registry (HLM/HCU) to see if any properties were defined during the tests, but I didn't find anything strange.... I tried to check some configuration file in the Embarcadero folder (in the user's system folders), but I didn't find anything that gave any information either! Finally, I went to the extreme and completely uninstalled RAD Studio, deleted folders, files and keys in the Registry... everything! And I did a reinstall from scratch! But nothing solved it... my new forms still having the TOPMOST property, this way, creating and calling the sub-forms through the "SHOW" procedure, always placing the sub-forms on the application's main form! Finally, my suspicion is that I bugged MSWindows and now Delphi will always be using create forms as TOPMOST... Has anyone been through this situation or can indicate a way to reverse this situation? watch the two videos using same code Video 1: before tests with SetWindowPos Form1 (main form) call Form2 (second form) using Form2.SHOW; clicking in Form2, it came to front clicking in Form1, it came to front OK!!! all it's working! Video 2: after tests with SetWindowPos Form1 (main form) call Form2 (second form) using Form2.SHOW; clicking in Form2, it came to front clicking in Form1, it DONT came to front now FORM2 is always on TOP.... 😭 Here the code used in my tests, nothing more than this 2 forms in tests (main and second forms) had all properties default and none code, basically empty! this code was in my Form1 procedure TMeuFormParaTest.Button1Click(Sender: TObject); begin SetWindowPos(Handle, HWND_TOPMOST, Left, Top, Width, Height, SWP_NOACTIVATE or SWP_NOMOVE or SWP_NOSIZE); end; procedure TMeuFormParaTest.Button2Click(Sender: TObject); begin SetWindowPos(Handle, HWND_BOTTOM, Left, Top, Width, Height, SWP_NOACTIVATE or SWP_NOMOVE or SWP_NOSIZE); end; after this code, all changed in my Delphi... new projects have its forms using "FormXXX.SHOW" as TOPMOST, and over my form caller (normally my Form-Main) AHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH! Im crazy with this! attached my project test with 2 forms and almost none code! VCL_Forms_always_TOPMOST_Now_in_New_Projects.zip ...
