While using a ListBox (and DesktopTable).

I save the contents in aText file as is:

Line 1: Column Header Text, Tab separated

Line 2: COlumns width \Tab Window location/size (Bounds)

Line 3 to EOL: data as Tab separation fields.

I worked with that window yesterday, using an external screen (and that window was there).

Minutes ago, I have a crash (this have to be checked) and… I noticed that my window is nearly entirely in the (not connected) external screen.

The Bounds saved values is: -1369,101,1439,768.

Usually, and unlike Windows, macOS deal with that (do not show a window when its last location is out of the curren view area.

So, either Golden Gate is in fault or Xojo 26r3.

Q1: Your opinion ?

Q2: For the Windows developer, how do you deal with that (I ask because Windows - \< Windows 11 - open and display off viewable area windows that was previously in an external screen…)

PS: the crash is because…

“Exception Message: Column 11 is out of bounds.”

I investigate right now.
