- Currently, the following problems are known to the developers of F-PROT:
-
- #1 Problem running F-PROT on some old IBM ThinkPad models.
-
- Some users of old IBM ThinkPad machines have experienced a total failure of
- F-PROT (DOS version) to run on their machines. The reason is the following:
- We use the CauseWay DOS extender program to create the DOS version. The
- ThinkPad models in question run some programs from SystemSoft, including one
- named CARDXTND.SYS, which uses an old 16-bit DOS extender from Rational,
- which is simply not compatible with applications made with other DOS
- extenders. In effect, while CARDXTND.SYS is running, no CauseWay
- application (or for that matter, application using other extenders) can be
- run, not even a simple "Hello World" program.
-
- This problem also exists with older Zenith Data Systems notebooks that
- also use SystemSoft BIOS and drivers. The executable PMEXT.SYS must be
- in CONFIG.SYS for power management to function properly.
-
- There is nothing we can do to fix the problem, and we consider it
- entirely the fault of SystemSoft - however, as the machines affected
- by this problem are mostly obsolete now, the problem is not considered
- serious.
-
- Unless Systemsoft fixes the problem (which we do not expect), CARDXTND.SYS
- must be disabled in order to run F-PROT on those machines.
-
- #2 Problem running F-PROT from a login script.
-
- We have received a single report of a problem that happens when F-PROT
- is run from a login script, where the program may randomly "hang" some
- time later. We have not yet been able to duplicate this problem, but
- we suspect it is due to a conflict with some device drivers or other
- low-level software.
-
- #3 Running the DOS scanner on a NT/Win2000 machine with the F-PROT VDD
-
- Currently, the DOS version is unable to disable the VDD (on-access) version
- of F-PROT, meaning that when the DOS version scans a file, the VDD does it
- too. This slows down the scanning and can be irritating.
-
- However, all users of the VDD should have the Windows version of F-PROT
- too, and we simply recommend that they use that instead of the DOS version
- if they have the VDD installed.
