Class is declared in IB_Components.pas, which is in the 'uses' clause, and parent folder is in the search path. Application compiles ok. At runtime I get exception eClassNotFound with message 'Class TIB_cursor Not found'.

Backtracking in call stack stops at CreateForm statement for a form not using TIB_cursot. That is used in a prior form, which appears to be created without errors. But I could be misinterpreting what the call stack trace is telling me?

App had been compiling fine with IBO5.2.0b7, prior to installing v. 5.3.1.b1862.

Any ideas appreciated.

Best,
