After installing KernelEx 4.5 RC1 each time I run Windows 98 Second Edition (Polish version) I get the message: "Błąd przy uruchamianiu programu Uruchomienie pliku KEXBASEN.DLL jest niemożliwe. Sprawdź plik, aby rozpoznać problem." ("The kexbasen.dll cannot start. Check the file to determine the problem.") There was no such an error in KernelEx 4.0 final2. I have the impression that KernelEx 4.5 works correctly, however, there may be a too small time limit? I have a Pentium MMX 233 CPU, 128MB EDO RAM, KernelEx Core v4.5.11, kexbasen.dll file: version 4,5,1,1 / 4.5 RC1, 95,5kB (97 792).
