## AI overview

ReactOS Newsletter 96 discusses debugging work on two application compatibility issues. A NULL handle and incorrect reporting of graphics operations were fixed so Microsoft Excel Viewer could work in ReactOS. A separate OpenOffice installer failure was traced to file unpacking behavior; one related problem was fixed while another remained under investigation.

## Source excerpt

Testing and Debugging The hardest thing about writing software is finding the source of bugs. Good testers are as such extremely valuable, and those able to use debuggers well even more so. Two issues were recently dealt with thanks to one such tester, Olaf Siejka. The first issue involved Microsoft Excel Viewer, an application that as its name suggests allows for viewing of spreadsheets but not editing. Word Viewer actually worked in ReactOS, and Excel Viewer's failure drew Olaf's attention.
