This may improve compatibility if Catsxp does not work well with all Chrome-specific handling. However, after removing the line, Catsxp may be treated as a normal application unless Sandboxie detects it automatically.
With the line removed:
- UseElectronDetection=y may still detect Catsxp during startup if its executable directory contains recognizable Chromium or Electron files. If detected, Sandboxie assigns the same Chrome image type, so the result will be mostly the same as keeping the explicit rule.
- DynamicImageDetection=y may detect it later when it loads chrome_elf.dll or a matching renamed Chromium DLL. In that case, Catsxp may run as a normal application during early startup. Some runtime Chrome-specific handling may begin only after detection, while startup-only handling may already have been skipped.
- If neither detector recognizes it, Catsxp remains unclassified and does not receive image-type-specific Chrome behavior.
The difference can affect compatibility features such as Chromium command-line flags, Chrome Secure Preferences handling, desktop and WindowStation workarounds, Win32k hooks, WebView2 handling, and other browser-specific paths. It does not disable Sandboxie’s general isolation.
In practice, removing this one line is a targeted compatibility test. It may help if forced Chrome classification is causing Catsxp problems, but it may also remove compatibility handling that Catsxp needs. The result depends on whether, and when, one of Sandboxie’s automatic detection paths classifies the application.
