Repeated "SetupSysMenu: GetSystemMenu() failed for HWND [memory address]" upon running TBrowser

ROOT
1

I’m getting a cascade of GetSystemMenu() failures after launching and using TBrowser (having previously initialized it with a macro). TBrowser itself seems to function normally when this is happening, but it’s strange that it’s appearing in the terminal. Additionally, it only shows up in one particular terminal, even if I have multiple terminals open and am running ROOT in the other one. This occurred when I had nano open in the terminal where the errors appeared, and wasn’t running ROOT there at all. Why is this happening?

I also get the same error once right before the startup “WELCOME to ROOT” message in the terminal.

root [1] TBrowser *tb=new TBrowser root [2] SetupSysMenu: GetSystemMenu() failed for HWND 0x2f05b4 SetupSysMenu: GetSystemMenu() failed for HWND 0x3005b4 SetupSysMenu: GetSystemMenu() failed for HWND 0x2905ca SetupSysMenu: GetSystemMenu() failed for HWND 0x30056a SetupSysMenu: GetSystemMenu() failed for HWND 0x3405b4 SetupSysMenu: GetSystemMenu() failed for HWND 0x39056a

Pressing the enter key brings the user back to the root [2] prompt.

Hi,

This is most probably coming from Cygwin, SetupSysMenu: GetSystemMenu() is not specific to ROOT
You can try to find which window is causing the issue with a tool like GUIPropView (for example), since the error message is giving its HANDLE
