Files Opening in Read-Only Mode

 

When you open an existing Mandrel datafile, a ‘Read-Only’ notice may sometimes appear on the screen, even though the file is not in use elsewhere. You may also see a Windows notice to the effect that <filename> is locked for editing. Data entered into the file cannot be saved, unless you save the file under a new name.

 

Cause

This phenomenon is caused by an interaction with the Windows Indexing Service. Microsoft has acknowledged that this is a known problem in Windows, and has provided a fix for the Vista and later operating systems, but not for the XP or earlier operating systems.

 

Indexing was introduced by Microsoft as a performance enhancer for file searches, but because it often occurs while users are working it can temporarily lock files at inopportune times. Many people choose to disable the indexing system on their computers for this reason.

 

Solution for Windows XP or Earlier Systems

The only effective solution for Windows XP or earlier operating systems is to switch off the indexing system. This will not have any effect on other operations unless you use the desktop search facility frequently. Without indexing, the search facility still works but will be slower because Windows will fall back to the item-by-item search mode. To switch off the indexing system:

 

1. On the Windows Control Panel, select Administrative Tools, then select Services.

2. Scroll down to Indexing Service, then click on Stop.

3. Right click on Indexing Service, then select Properties, then set Startup type to Disabled. This last step is necessary, otherwise Windows will switch the indexing system back on the next time you re-boot the computer.

 

Solution for Windows Vista

Microsoft has provided a ‘hotfix’ download for Vista to deal with this problem. To obtain this:

1. On your browser, go to http://support.microsoft.com/kb/983458

2. Click on the link View and request hotfix downloads

3. Select the hotfix for Windows Vista, and enter your e-mail address

4. Microsoft will e-mail the hotfix to you. You will need a password to open the file, which Microsoft will send with their e-mail.

 

If for some reason this does not work, or if you choose not to install the hotfix, you can just switch off the indexing system:

 

1. On the Windows Control Panel, select Administrative Tools, then select Services.

2. Scroll down to Windows Search, then click on Stop.

3. Right click on Windows Search, then select Properties, then set Startup type to Disabled. This last step is necessary, otherwise Windows will switch the indexing system back on the next time you re-boot the computer.
