HTML-Kit 292 makes it easier to preview HTML documents in several ways, including through a web server. When previewing documents through a web server, sometimes the server may lock files that are being served. To get around this issue HTML-Kit 292 may, in some cases, create a copy of the file. If you preview read-only files, the read-only attribute may get reset.

You can update HTML-Kit 292’s settings as described below so that read-only files won’t loose the read-only attribute during this process.

1. Download hkSetCachedWrite plugin. The download button is located in the Download section of the page (in light brown color, as of this writing). Save hkSetCachedWrite.zip file to a temporary folder. You do not have to expand or unzip it.
2. Select "Tools | Install | Install Plugin" from HTML-Kit 292’s main menu. Select hkSetCachedWrite.zip and click OK.
3. Close 292 and open it again.
4. When 292 restarts, you should see a "Settings" tab on the Actions Bar with the hkSetCachedWrite icon (a small folder icon).
5. Invoke hkSetCachedWrite by clicking its icon on the Actions Bar or by selecting it from "Actions | Settings" menu option.
6. When prompted, click "No"
7. Restart HTML-Kit 292. Read-only file attribute will be preserved from this point forward. Note that if you reinstall 292 you may have to repeat these steps.
