Thanks, Razzak for your quick and detailed help. This is a standalone installation (not server) on my computer and the chm files are in the RBG8 (or the corresponding RBGx directory for the other versions).
In this particular instance, the fixes below didn't apply, I tried them, but there wasn't anything wrong with them to start. The culprit appears to be IE7 or perhaps some security updates applied to that. I uninstalled IE7 and now I have all the help files showing up in Rbase Turbo V-8, R:Base 7.5, etc., no muss, no fuss. I'm going to experiment to see if I can figure out exactly which part of IE7 caused this to fail.

Where are R:BASE Help (.CHM) files installed? There are several possible reasons why your .CHM, e-books, and documentation files are unreadable, and eventually crashing R:BASE. 01. The CHM viewer component is not properly registered on your PC. The system file <WINDOWS>\system32\hhctrl.ocx may get missing, corrupted, or unregistered. Solution: Run "regsvr32 hhctrl.ocx" command from the command line to register the library in the system. 02. A security update for Windows XP may block access to CHM files Windows XP security update blocks active content in CHM files to protect your system security. Additional information is available at: http://support.microsoft.com/kb/896054/ Solution: Run Windows Explorer, right-click on the CHM file, and select Properties from the popup menu. Click on the Unblock button immediately below the Advanced button on the General page. Click Apply to show the content. Once the CHM file has been unblocked, the Unblock button disappears. 03. The CHM file is in the restricted Internet zone When a CHM file that you are trying to access is stored remotely, e.g. on the network drive or on a remote server, you may also get in trouble. If the associated security zone is restricted, then CHM files won't be displayed as well. Solution: Modify the ItssRestrictions registry entry to enable a specific security zone. Follow these steps: 01. Run 'regedit' command from the command line. 02. Locate and then click the following subkey: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp\1.x\ItssRestrictions Note: If this registry subkey does not exist, then create it. 03. Right-click the ItssRestrictions subkey, point to New, and then click DWORD Value. 04. Type MaxAllowedZone, and then press ENTER. 05. Right-click the MaxAllowedZone value, and then click Modify. 06. In the Value data box, type a number from 0 and 4, and then click OK. The values settings are 0 = My Computer 1 = Local Intranet Zone 2 = Trusted sites Zone 3 = Internet Zone 4 = Restricted Sites Zone For most CHM files, the value of 1 should be enough to allow use without opening up access from/to remote CHM files. 07. Quit Registry Editor. Warning: Enable only those security zones that you trust. Do not enable security zones about which you are not sure. Hope that helps!
