Hi Tomasz Grysztar. I'm working on a project that is not single executable, it is separated into DLLs and EXE. Thus, when I'm opening multiple source files from Windows command line I can edit and save them normally. Buy, when I try to compile them, FASM says me: "Error: source file not found". Then, if I try to save source file, fasm suggests me to save it as (via save file dialog), although FASM already knows its location.

You can repeat my actions following next steps:

1. Create or get some test FASM souce codes (for exemple YourSource.asm, YourSource.inc, YourDefinitions.inc).
2. Create text file and write to it next line

Save this file as windows command line (*.cmd or *.bat) file.

3. Run it. This action will open FASM editor with "YourSource.asm", "YourSource.inc" and "YourDefinitions.inc" tabs. You can modify then and even save.
4. Now go to main tab (here is "YourSource.asm"). and try to compile sources. And then try to save sources.


Respects.

Thank you for the report, but I was unable to reproduce it on my machine with the steps you provided, even when I tried to repeat everything faithfully, including all names and environment variable.
What version of Windows are you using?
Does it depend on the path to the working directory where you're doing it?
Perhaps there are some special characters in the path that are triggering the bug?

OS: Window 10, I have no special characters, even spaces in path. That was my fault, the method described by my in post above was simplified and it really works correctly. But, i decided when my trouble appears: You need to put source file into at least one-level subdirectory (for exemple "Src") and call cmd file modified as next: I've just tested it. It really causes errors I described in post above.

Thank you, now I know what happened. I have updated the 1.73.24 package with the new IDE interface version 0.99.06 - please try it.

I've tried. It works fine. Thank you so much
