New instance of JMP® is opened each time a new file is opened

[#1]

Hi everyone,

I've searched around and found some solutions to the problem that I am having, but none of them have seem to worked for me, so I thought I would just ask again to see if anyone might have some additional insight.

I help train colleagues at our company in using JMP and one problem that we regularly encounter is that if someone opens a file from Windows Explorer while they already had another JMP file open, the new file opens in an entirely different instance of JMP, thus cluttering up the taskbar and making it impossible to carry out tasks between the two files (like merging the two tables, etc). Obviously, once we realize that is the problem, we save the file, shut down the second instance of JMP, and reopen the file in the original instance, but this is a problem that frustrates many of us, so I thought instead of being frustrated, I would ask to see if anyone had a solution.

I have tried the solutions discussed in https://community.jmp.com/t5/JMP-Knowledge-Base/Problem-Note-52261-New-instance-of-JMP-is-opened-eac... but although it perfectly describes the problem, the solutions don't seem to help the situation. I have also tried what I have permission to do [based on my operating system permissions], but likewise, I have not been able to solve the problem.

Thanks in advance for any insight!

Thank you Patrick, strange as it seems, this is the solution that worked for me!

Note on this solution:  It didn't work at first but when I repaired the installation of JMP and then tried the notepad trick it work!

@althompsonphd The note reference in your original post is for Windows only.  We generally do not see this behavior from Mac OS.  Since Mac OS is driven by configuration files and not a Registry database like Windows, I would recommend deleting the related JMP configuration files.  JMP will rebuild them on the next launch.  However, you will need to supply the JMP license file or serial number again.

The steps below come from this JMP Note 678317

Remove JMP User Customization Data

1) From Finder, select Go > Go to Folder…

2) Type ~/Library and hit Enter

3) In the user’s Folder, open the Application Support folder

4) Select the JMP folder and drag it to Trash

(You might have to provide your password to complete the action)

5) Navigate back to ~/Library

6) Open the Preferences folder

7) Find all the “com.sas.jmp” files and drag them to Trash. 

There will be at least com.sas.jmp.plist and maybe more than one.

If the step above do not resolve your issue, please contact support@jmp.com to open a Technical Support case to further investigate this issue.
