How many different FileMaker files do you have open (possibly hidden in the back ground) when you are doing this typing?
I've seen a few issues where having a number of different files open (all with their own window) made for painfully slow updates to typed in data--but this seemed to be due to having one or more windows open that had layout objects that needed to update regularly in response to other users making edits in those hosted databases, so this may not apply to your situation.
Did you look for any updates to "typeIt4Me" when you updated Filemaker? Perhaps there's an incompatibility between v10 and the version of typit4me that you are using.
Thanks for reply Phil.
This has always been a single file (table) with no dependancies : it is simply a word processing file with all records filed by type and ID number. There's very little to it apart from a couple of large text fields for typing in (several pages long).
As for TypeIt4Me, I now don't think it's an issue as ALL typing (whether abbreviations or not) is slow into those fields. There is a noticeable delay before the words I've typed actually appear. In FM6 it's perefectly speedy.
