In JMP16.2 -- it appears (on a windows PC) if the user goes to File/Open and changes the filetype to All Files *.*
In Jmp 17.it appears if the user does the following (*)
- change the filetype of File/Open to
All Files *.* - close the file open window
- reopen the window.
On the other hand, it disappears if you select another file type from the drop-down menu.
Sometimes, it stays hidden till you start again with (*) and sometimes it just appears as soon as you select All Files *.*, without (*)
Fortunately, with Jmp17 the setting changed from default on to default off
What remains even in JMP17 as a problem:
If you click on the file in the Recent Files list to open it again, Jmp seems to assume that the checkmark is on and either opens the file with the default program or asks for a program to open the file (if the extension is unknown.)
So, if you work on a Windows PC and have files with their own file name extension, always open them via File/Open - even if the files show up in the Recent Files list ...
