Convert to API 2 causes crash

[Chris_Halford]

I have a project that I cannot convert to API 1. Not sure why because there is nothing “fancy” in it.

I have a number of small windows with only a few controls in each; these converted easily, with no compilation errors, and worked OK when tested. Such steps can then be applied to the clean copy.

Which OS do you use? If it’s macOS do you have a crash log?

[Chris_Halford]

I am on Mac. It’s not a hard crash. I get a friendly message from Xojo that it’s about to shut down so I don’t see a crash long.
Maybe Xojo stores something somewhere I’m not sure of.

I’m nervous I’ll have to rebuild this project line by line to get it current.

how far back was the codes for that app ?

Do you mean which version of Xojo?
I don’t know when I originally wrote those parts but they compile and run fine in the current version of Xojo as long as I leave them as API1
