What version(s) of DOSBox-X have this bug?

0.83.18 both SDL1 and SDL2 32-bit

Describe the bug

DOSBox-X has trouble with WordStar for DOS 7.0 macros that access the file system to overwrite or delete existing files.

The attached macro SAMPLE.WSM copies DOSBox-X's README.TXT from DOSBox-X's drive Z: to a file named TESTFILE.TXT in the current folder, and then copies TESTFILE.TXT five times to files named COPY1.WS, COPY2.WS, COPY3.WS, COPY4.WS, and COPY5.WS.

I've provided error handling in the macro to deal with prompts to confirm overwriting or for files not found, so that it should run successfully regardless of whether TESTFILE.TXT or COPY?.WS already exist.

Furthermore, the macro sets WordStar to help level 0 while it is running, which turns off all confirmations, so the error handling is actually redundant. The macro should simply run to completion with no prompting for confirmations by the user, no matter how many times the macro is invoked.

If you run the attached macro SAMPLE.WSM from WordStar's OPENING MENU (by selecting MP, for Macro Play), it succeeds the FIRST time, when none of the files it tries to overwrite already exist.

But if you run it a SECOND (or subsequent time), it will crap out, first by asking the user for confirmations that should not be required, and, second, by dropping parts of commands.

The macro runs flawlessly under vDosPlus by @Wengier as well as TameDOS, but fails under DOSBox-X.

Expected behavior

WordStar should be able to overwrite or delete existing files using its own file-copy or file-delete commands from within a macro.

Steps to reproduce the behaviour

Unzip the attached WordStar for DOS 7.0 macro named SAMPLE.WSM to the folder that contains your WordStar macros (commonly either C:\WS or C:\WS\MACROS).
Run WordStar for DOS 7.0
From WordStar's opening menu, run the macro SAMPLE by selecting M then P (for Macro Play) or Alt-U,M,P if using the pulldown menus)
Macro will run flawlessly the first time, as none of the files it tries to overwrite yet exist.
Macro will fail badly on second and subsequent invocations since the files it is trying to overwrite do exist. SAMPLE.zip
