I have a big problem I cannot solve.
I developed a very well working solution (on RP2 and RP3) on Xojo 2017 Release2 and 3. Application is serial data receiver, with GUI and data saving to server database.
In December '18 I updated my test system (MAC OSX based) to Xojo 2018R4 and I compiled the same working project for RP3 (the same running fine the other solution made with previous Xojo version) but when I launch it, nothing happens.
I believed I made a mistake and I tried many times, updated RP, changes Raspberry, SD, USB, etc... still the old working, but not the new one.
No error, but nothing happens, no GUI, nothing.
I just updated to Xojo2019R1(I have Pro license) and still nothing happens. Still like not working at all.
What do I make wrong?
Should I install something differently on RP to run the new packages 2018R4/2019R1 compared to 2017R3 version?
I couldn't understand and still using the old Xojo2017, but why????
I'm running late on projects as I cannot find out what's wrong.
Thank you for any support or suggestion you could provide me
