"one of these files"...
Are these all copies of the same files or variations produced from one original file?
Do other Database file on the same computer function normally?
If so, try running a recover on these files and test the recovered copies even if recover reports no problems found with the file. (Recovered files have rebuilt indexes and other settings are returned to "factory spec" so even when no problems are found/fixed by recover, the recovered file may function differently than the original.
Look if you've sorted relationship.
I had one which was sorted by the unstored fields it was triggered by ! So this created a kind of loop. I couldn't go to a layout due to that field on it.
I spent months to figure out why !
Thank you for your reply. I am beginner level with FMP. I think relationship you mention only applies if I have more than one table, and I "relate" a field from one table to another. To my knowledge, I only have a single table holding my data, which is an catalog of my digital images. One field does contain the filename/path to the image, located elsewhere on my computer hard drive, but I don't think there's a "relationship" involved there. thanks again.
Thank you for your reply. Yes, the three files have the same field structure. They are image databases to help me locate images by date, person, genealogy number, place, etc; and they contain a thumbnail of the image, and the image filename/filepath on my hard drive, and display the image itself. The three files/tables are similar, just with different sets of image data for different parts of my family tree. All three files have same problem of slow/not responding.
I tried the "recover" operation you suggested, on one of the files, and it does seem to respond better. I'm going to play with it some more, and try it on the other files in a more scientific method way (i.e. time an operation, recover the file, and then try the same operation again, and compare.) Thanks so much, I'll let you know how it works.
