Patch for known Informix BUG?

Is anyone aware of a patch for a known Informix bug in 4GL reporting. An existing 4GL reporting module works using V4.11 of the tools, but does not work in V6.04 of tools. Detail :- FIRST PAGE HEADER PRINT details PAGE HEADER PRINT details ON EVERY ROW PRINT details Problem :- It prints the first page header first then the rows and then the page header. We will only use a 4GL work around as a last resort. Also, there is only one single mention of a reports page header bug in the release notes and it does not apply to this particular case. We are aware of a fix in 7.x of the tools. This is not a solution as we have compiled and tested hundreds of 4GL modules in V6.04 and as a result we do not want to start regression testing. We fail to belive that a BUG like this has been around for so long. i.e. V4.11 up to 7.x Perhaps we should rewrite our system in assembler! Thanks to any players ....
