Symptoms

When you open a document and the ActiveX thumbnail control included with Web Access is not installed, Internet Explorer will perform one of the following based on its security settings:

• Automatically install the ActiveX control.
• Present you with an option to install the ActiveX control.
• Automatically decline to install the ActiveX control.

Regardless of which option occurs, if you then add a highlight, redaction, or stamp and close the document window, Internet Explorer becomes unresponsive and you will have to end the process. If you chose to install the ActiveX control, this issue should no longer occur.

Workaround 1

If Web Access is used in an Intranet, configure Internet Explorer to automatically download signed ActiveX controls for sites in the Intranet Zone. A network administrator can configure Internet Explorer's security settings without having to manually perform the process at each client computer.

To configure Internet Explorer Security Settings from Windows XP Service Pack 2

1. Click Start and then click Run.
2. In the Run dialog box, type the following and click OK to load a MMC console shell:

   mmc

3. From the File menu, click Add/Remove Snap-in.
4. In the Standalone tab, click Add.
5. In the Available Standalone Snap-ins list, select Group Policy Object Editor and click Add.
6. In the Select Group Policy Object dialog box, click Browse.
7. In the Browse for a Group Policy Object dialog box, select the appropriate domain on which you want to change group policy and click OK.
8. Click Finish to add the snap-in.
9. In the Add Standalone Snap-in dialog box, click Close.
10. In the Add/Remove Snap-in dialog box, click OK.
11. In the MMC console, expand the MyDomain Policy item.
12. Expand Computer Configuration.
13. Expand Administrative Templates.
14. Expand Windows Components.
15. Expand Internet Explorer.
16. Expand Internet Control Panel.
17. Expand Security Page.
18. Select Intranet Zone.
19. In the right-hand pane, double-click Download signed ActiveX controls.
20. In the Download signed ActiveX controls Properties dialog box, select the Enabled option.
21. Click OK.

Workaround 2

Configure Web Access so that the ActiveX thumbnail control is disabled. Internet Explorer will not try to install the control and this issue will not occur. Be aware that this will disable the ability to drag and drop thumbnails.

To disable the ActiveX thumbnail control

1. Browse to the ASPs subfolder of the Web Access installation folder. By default, the path is located at C:\Program Files\Laserfiche\Web Access\ASPs.
2. Use a text editor to open Settings.inc.
3. Look for the following line:

   Const ACTIVEX_THUMBNAIL_DISPLAY = True

4. Change the line to read:

   Const ACTIVEX_THUMBNAIL_DISPLAY = False

5. Save the change and close the text editor.
