If you are updating from a version of the extend Interoperability Suite earlier than version 10.4.1, you need to be aware of the following changes that might affect your existing applications:
On Windows platforms, there has been a change in the way files are handled for a bitmap control. In previous versions, changing a BITMAP-HANDLE for a bitmap control to a null value (0) did not correctly erase the existing bitmap, and instead left the previous bitmap showing. This has been corrected in this version, and this correction affects all previous versions. To apply this correction to applications compiled using a previous version, you must recompile with version 10.4.1 or later, for 10.4 semantics or later.
