At some point, I think after adding a decision block, I wasn't able to use the dropdown menu/list in any of my activity. The console gives the following lines:
exception: size_t treewin__OnCommand__flexguicontrols(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam, TreeWin * t, int mx, int my)
ex: treewin__OnCommand__flexguicontrols
exception: size_t treewin__OnCommand__(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam, TreeWin * t, int mx, int my)
ex: treewin__OnCommand__
exception: size_t treewin__OnCommand(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam, TreeWin * t, int mx, int my)
exception: treewin__OnCommand
ex: OnCommand
I tried going back to older version but any of the "recent" versions will now have the same issue.
I can still edit the code in any of the insert boxes, it is truly only the GUI (also present in the error code) I believe.
