Solution for TomTom cache errors on Palm OS

I have been dealing with errors on the Palm OS for quite some time when running TOMTOM Navigator 5 and 6. Even though I have been able to free up a lot of internal memory in the Treo 650 using the Japanese program PowerRun
I still got the message "DB Cache memory full", upon which TOMTOM would not load. It required a soft reset at each occassion, an irksome problem.
I tried using dbcache DbCacheTool
also coded in Japan, however this was never really successful in freeing up the cache memory.
Today I finally discovered what I feel is a relatively stable solution to this issue-
I am using a new release of Resco's Locker Link
to keep the apps that I use most often locked in RAM (including Navigator!),
and I am using a new application that I discovered today called flushit! to clear out the internal cache and free up plenty of space for GPS navigation.

I am absolutely thrilled with this new .prc file, it is simple yet elegant, a little rough around the edges I admit (screen flickers at times when clearing out the NVFS), yet the results are undeniable. I can now start TOMTOM without resetting the unit, saving a great deal of time.

as an addendum, I am floored by the new upgrade to TOMTOM Navigator- version 6 is a huge upgrade and the map of North America, while huge at 1.4GB, is a momentous achievement by the Dutch company. The fact that I can navigate to Canada and back without changing maps, and that there are points of interest for every city in the United States and Canada, is almost incomprehensibly cool.
