Sometime Nanovna freezes while moving the marker with the pen

[simonepernice]

Hello,

If I move the marker with the touchscreen the NanoVNA sometime freezes. I noticed it never happens at startup when the stop frequency is set at 900MHz. The freeze looks more likely when I increase the frequency end, for instance at 2.5GHz.

I am using NanoVNA V2 with 3.2 inch display and I have installed the firmware nanovna-v2-20201013-v2_3_2.bin from the following link: https://nanorfe.com/downloads/20201013/nanovna-v2-20201013-v2_3_2.bin

Thank you, Simone
