Is there a finite limit to the number of records that I can have in DJO in my phone? The past couple of days it has been freezing or showing a blank screen when I change/save items. I can do a couple of them, then it acts up.

================================================== =
Samsung Galaxy S5, Android 6.0.1 (security patch level Apr. 1, 2017)
DJO 4.3.3 build 998; CL 7044
Win10 x64, AU update; PalmDesktop 4.2 (running in compatibility mode for Windows XP)

USB sync --- manual syncing, as needed; one direction at a time
