ArcPad 8 Service Pack 4 won't save extension preferences?

[JulieLuetzelschwab]

We upgraded a Juno SC and a Nomad to ArcPad 8 service pack 4 and we have found if we check on a "non default" extension it will not save it once ArcPad is closed.  We use MrSid files regularly so I checked on the MrSid extensions and hit OK.  I was able to add the MrSid images and they drew up just fine, I saved my map.  I then opened ArcPad again and the same map and the MrSid images were gone.  I had to check the extension back on and then re-add the MrSid images.

This issue happens will all "non default" extensions, including the laser ones, GIF, etc.  It will be checked on while that ArcPad session is open, but if you close ArcPad and open again you have to recheck on these extensions.

Anyone have a fix?  Back to service pack 3 maybe?

I found a fix, but there should be an easier way.
Open \My Documents\My ArcPad\ExtensionPrefs.apx with WordPad and find the extension you want to stay checked on, for me it was MrSid, and change the "false" to "true."
name="MrSID" enabled="true"

Cliff from the Trimble Help Desk got back to me today and said the problem is the ExtensionPref.apx file is READ ONLY.  To fix this problem with Windows Explorer you can copy that file from your GPS unit to your computer, right click on the file and uncheck the READ ONLY button, then copy the file back to your GPS unit.

Or delete the *.apx on your PDA. Next time you start ArcPad a new (editable) one will be created.
This is a full reset. In this case you must uncheck unwanted extensions in "advanced options" again.
