I can't tell which forum this issue belongs under, but here's my problem. I frequently get the message "this record cannot be modified in this window because...", I know the reasons for this error message usually involves the commitment of records. However, what happens is that FM for some unknown reason has opened a new window (It appears in the Widow menu). I do not create new windows while I work and none of my script have this script step. What are new windows being created? This is not the same thing as switching layouts (or is it)? I've tried various tests by entering data on a layout field and in a portal then switching to a layout with the same field. But I can enter data in the active field with no error messages. What gives?

How about a script trigger on one of the fields?

 

You might want to post a copy of the file.

This is normal behavior and it happens when FM needs to open a related file because you wish to display one of its fields on a layout (or a calculation needs to display which uses a value from that related file).  But if you have a specific issue that is concerning, as Lee suggests, it would be best to see the file. 

What do you mean by related "file" ?

Every layout is based upon a table occurrence. If it has a relationship to a table occurrence in another file AND the current layout has anything which requires accessing this other file, it needs to open the other file in the background (appearing in the Show Window). I suspected this might be what is happening.

No, I'm not working with another file. There is no relationship to a TO in another file. When I click the Window menu, I sometimes see list of file names: 1. file name, 2. file name, 3. file name, etc. where the file name is the name of the current file. I have no idea why these are appearing.

Do they have a dash and then a number after them?  You might check File > Manage > External Data Sources and see what is there.  Do you ever perform a GTRR ( Go To Related Record ) and maybe accidently specify open new window?  We'll probably need to see the file (zipped). 

 

Added:  Also, is this file served and is it on its own server without file sharing on it?
