Clicking link in LINE chat room while Maxthon is running fails to open link page

[scottchu.tw]

I experienced a strange problem:

test 1.When Maxthon is not running, I click a link in LINE chat room, it will open Maxthon with this link page correctly. But If I click any other link in LINE chat room further, it has no response, i.e. it won't open 2nd link page in Maxthon.

test 2.If I run Maxthon first, then I click any link in LINE chat room, it has no response, i.e. No link page will open in Maxthon.

test 3. I check default program in setting, it's Maxthon alright.

According to the test, I click any link while Maxthon is running, it won't open the link page in Maxthon.

test 4. Then I change default program to Chrome, retest above steps again, all works fine.

It seems the problem is coming from Maxthon. The symtom is when setting default browser to Maxthon, while Maxthon is already running, when I clink any link, it trigger a calling to ask Maxthon to open link but Maxthon can't recognize or failt to open link. However, when setting default browser to Chrome, everything works fine.

I'm using version 7.1.8.9600 in Win11.

What could be wrong?
