eTrex SE FW 4.20 freeze wenn Aktivität gespeichert wird. Nur Hard Reset hilft. Firmware Update verfügbar ?

When saving an activity at eTrex SE the device freezes. only hard reset helps. seems the editing name prior saving is a workaround. in adition weather forecast hangs after the first two status pages - endless circle, but no freeze. is there a firmware update ? (maybe a beta) - saving activity with freeze is annoying...
