# Web browser Internet Explorer

### Problem 1

An error has occurred in the script on this page.

#### Solution

When you launch a ***Website*** in Internet Explorer directly (external mode), the script errors are handled by the browser, so they are not displayed.

In embedded mode, you need to enable the ***Hide script error*** in the properties of your session.

### Problem 2

Browser extension does not appear in the toolbar but it is installed.

#### Solution

This issue occurs when a specific option is unchecked for IE in ***Tools – Internet Options – Advanced***.

The option is called ***Enable third-party browser extensions*** After enabling this option, IE must be restarted.

### Problem 3

Embedded html content is not rendered with the latest Internet Explorer version.

#### Solution

By default Remote Desktop Manager does not use the latest IE version (emulation mode). This can be changed in ***File – Settings – Type – Web, IE Mode***.

### Problem 4

Accessviolationexception - attempted to read or write protected memory.

#### Solution

When a crash occurs in Remote Desktop Manager while using some ActiveX in IE, it is often caused by Data Execution Prevention (DEP). DEP is a security feature included in Windows. It is used to prevent an application or service from executing code from a non-executable memory region.

To fix this, change the DEP settings for the application as follows:

1. Right Click ***My Computer – Properties***.
2. Choose ***Advanced System Settings***.
3. Click the ***Advanced*** tab.
4. Click ***Settings*** under ***Performance***.
5. Select the tab ***Data Execution Prevention***.
6. Add ***RDM*** to the list.

### Problem 5

Launched external windows (such as ie) popup in the background.

#### Solution

You may have noticed that when you launch items such as IE windows from within Remote Desktop Manager, they pop-up in the background.

The ForegroundLockTimeout registry value for the User’s Profile has to be modified from the default of 200000 down to 0:

\[HKEY\_CURRENT\_USER\Control Panel\Desktop]

"ForegroundLockTimeout"=dword:00000000

Please note that some programs that have an extensive library of add-ons (Like MS Word) may take the focus every time the add-on performs an action. You have to observe the reaction of your most used programs and judge what is the setup that works best for you.

### Problem 6

Unable to copy from ***Overview***.

#### Solution

Enable the option: ***Use embedded Microsoft Edge for overview panel*** in ***File – Settings – Advanced – Microsoft Edge***.

Enable the option: ***Enable context menu in Overview*** in ***File – Settings – User Interface – Dashboard***.

Open the ***Internet Properties*** dialogue. Go to ***Security – Custom level***, scroll down to ***Allow Programmatic clipboard access*** and select ***Enable***.
